Psvane Tubes – What Now?

The PAST:

As of Feb 2021, Grant Fidelity no longer directly resell Psvane branded vacuum tubes due to then declining re-tested tube measurements for the inventories we received, and no agreement could be reached then with the Psvane factory management (rumor said that the factory was then preparing for stock IPO hence chasing for sales volume and QC was oversighted. The IPO plan was eventually cancelled and could not proceed.)

What NOW?

Psvane now has adopted a more ‘direct sales’ mode and abolished much of the previous distribution method. Namely:

  • Two (2) new exclusive series – Summit Series (the ultra high end) and Horizon Series (the mid-range everyday value products) – are sold by Psvane’s own e-Commerce store on Amazon and AliExpress. They are NOT sold by any previous resellers or dealers in and out of China. Psvane was able to capitalize on 100% profit of these two series from the beginning to the end of the entire supply chain, ie. from factory production all the way to retail post-sale support.

  • Other previous high end series, such as ACME and Western Electric Replica (now called Legend) series, are still sold through conventional resellers in China and abroad, and many Chinese vendors sell to overseas market themselves via AliExpress.

  • Even older series such as T & TII Series (grey bottle) and Z-series (black bottle) are said to be bought out by larger Chinese dealers with lumpsum performance deposits paid to the factory upfront, and those tubes are sold also on AliExpress platform to overseas.

  • Psvane in the past produced multiple trenches of ‘dealer exclusive’ wholesale lots such as ‘Cossor by Psvane’ tubes and those tubes are also re-sold through sub-sellers on AliExpress etc.

In summary, LOTS of Psvane tubes are on the market from various channels and vendors – customers need to use good judgement to purchase from reliable and credible resellers.

Below are the Psvane Summit Series offerings – directly sold by Psvane’s own Amazon Store. We deem it as a credible and reliable vendor channel as it is indeed factory direct and likely return and warranty are handled relatively generous. Your purchase on Amazon is protected by Amazon policies which are extra layers of certainty of the uncertain tube world.

(Disclaimer: Grant Fidelity is sharing the product links for information in the role of Amazon affiliates only – we do NOT provide Psvane product consultation, order fulfillment nor post-sale warranty on any Psvane products.)

Shipping from US Warehouse now available!

With the complicated US customs clearance with carriers and anticipated processing backlogs in the upcoming holiday shopping season (from November to January), we have pre-stocked some of our ‘best seller’ tubes to a partner fulfillment warehouse in Michigan, USA, to offer our US customers more predictable delivery time.

At this time (Oct 2025), the following models are in stock ready to ship from MI, USA:

6SN7 Top 10% Best Grade pairs (including Linlai™ Global Elite E-6SN7 & our best special edition GF-Select 6SN7-SE)

300B Top 10% Best Grade pairs (including Linlai™ Global Elite E-300B flagship tubes)

We will replenish the stock in the US from time to time. If pre-stock runs out, your order will be reverted to be shipped from Canada with duty tax paid as usual.

Share your 90-day plan and help us to plan inventory ahead: If your intend-to-purchase stock is currently not available in the Michigan warehouse, please submit an ‘Expression of Intention to Purchase’ in this form for us to better predict future inventory needs from the USA. (Please note this is not a purchase commitment from you, nor a guarantee of stock from us – it is solely for information purpose and logistics planning.)

US Tariff & Shipping Guide

This post will be updated frequently with US tariff policies changes.

All US destination orders are now shipped with tariff prepaid by us to expedite and simplify order shipping.

US receivers will NOT receive a surprise bill at the time of delivery.

All actual tariff related charges paid to US Customs by us via couriers, including associated fees on top of the tariff itself, are 100% non-refundable. US Customs do not accept any tariff / duty claw back under any circumstances, even if an order is later on returned for ANY reason at ANY time. This is the policy by US Customs and there is no exception.

For the coming holiday shopping season:

Our STRONGEST advice is to shop EARLY and get your order in BEFORE November 1ST. Peak season has VERY HIGH shipping damage due to unavoidable rough handling with ALL COURIERS. We may restrict outbound shipping during that time to control losses by shipping damages.

Thank you for working with us through this Tariff time!

Ship to Europe: Get 50% tax bill rebate

European countries request all imports of any amount to be subject to VAT / duty assessment by local authorities.

Post office & couriers in Europe will calculate duty at the time of parcel import based on the value of shipment, and collect it from the receiver at the time of delivery.

By filling in your tax ID on checkout page of your order, it will expedite order processing through customs in Europe. We do not sell data to any marketing agency – this tax ID is only used to create shipping documents to expedite your order customs clearance with your country’s authority. Otherwise your country’s customs have to reach out to you, wait for your response in order to process your order import clearance. This manual process may take extra long time. We strongly recommend you to fill in tax ID in your order to expedite order customs clearance and delivery in Europe.

As each European countries have different VAT rates and/or duty regulations / customs processing fees, we do not include VAT or duty amount in our website pricing.

Most western European countries now have digital customs processing which is fast and efficient – receiver usually gets either SMS text messaging or email notification when VAT/Duty amount is due for payment before a parcel can be released. Please be sure to check your email and/or track the parcel with provided tracking number – you usually can pay for the VAT/Duty bill online before the parcel reaches your local courier depot.


We can rebate 50% of your import charges:

We now offer to refund 50% of your European import charges (combination of import fees, VAT and duty) up to either 50% of the import charge bill, or 50% of the amount of your country’s VAT, whichever is LESS.

This rebate offer is only valid for items purchase at ‘regular price’, and not valid for ‘on sale’ items, or items purchased with promotional coupons applied. Our pricing and business model cannot sustain ‘discount + rebate’ while still maintain economically viable and sustainable. We appreciate your understanding of this ‘no double dipping’ policy.

Rebate Example 1:

If your country’s VAT rate is 20%, your order item total price (net of insurance and shipping etc) is 500 Euro and you received an import charges bill for the amount of 85 Euro. We will refund you the less of: 1) 50% of import charge bill = 85 Euro X 50% = 42.50 Euro, or 2) 50% of VAT of the item price = 500 Euro X 20% VAT X 50% split = 50 Euro. Your final refund from us will be 42.50 Euro.

Rebate Example 2:

If your country’s VAT rate is 25%, your order item total price (net of insurance and shipping etc) is 1000 Euro. You received an import charges bill for the amount of 320 Euro. We will refund you the less of: 1) 50% of import charge bill = 320 Euro X 50% = 160 Euro, or 2) 50% VAT of the item price = 1000 Euro X 25% X 50% split = 125 Euro. Your final refund from us will be 125 Euro.

How to claim 50% import charges rebate:

This 50% split rebate will only be issued as refund to your original order payment method, upon presenting the official import charge bill issued by your country’s customs, and subject to verification.

The bill can be sent to us as scanned .pdf file or .jpg image and can NOT shown being altered by any means. We do not accept emailed message of ‘I was charged for and paid this and that amount’ or a portion of your credit card bill. It must be the official tax bill from courier or your country’s customs authority, showing the shipment tracking number to match with your order.

Once you have claimed the 50% split rebate, your order is no longer qualified for refund under any circumstances and any amount rebate issued will be sunk cost. Please understand the amount paid to a country’s customs and tax authorities cannot be clawed back by us under ANY circumstance.

We hope the above rebate policy will make international shopping less expensive for our European customers!

Importing to European Countries from abroad

When you shop local in Europe, usually the product price has VAT included.

However, we are a business located in Canada so our website price is net of any European VAT.

We can help you to manage the import cost to your country in a few different ways, to improve your purchase experience from abroad.

  • If you are sure that your country’s Post Office has automatic customs clearance process and provide an option for buyer to pay for import charges online with credit cards, you can communicate with us before order shipping, upon placing your order. In this case, we can set up the Post Office (Canada Post) shipping label with such import charges notification to be sent to us directly via email. Upon receiving the email from your country’s post office, we can pre-pay your import charges at our end then you receive your order with Duty and VAT paid.
  • At this time, we are aware that France (French Post) and Germany (Deutsche Post/DHL) offer automatic customs clearance and online payment by credit cards. If you know other countries in Europe offer the same clearance and payment options, please share with us to help improve customer purchase experience.

  • If your country’s Post Office does NOT offer automatic customs clearance and request in-person payment for import charges, we often can cover 50% of your import charges when certain conditions are met. See details HERE.

Happy shopping and we look forward to welcoming you to join our European customers!

Why buy E-845 Top 10% Best Grade from Grant Fidelity?

‘Why buy Top 10% Best Grade tubes from you? There are cheaper price on internet!”

A few top reasons:

  1. Our Top grade tubes have STRONG emission capacity = LONGER tube useful life. (For example: Our top grade Elite E-845 tubes start with minimum 90% full emission up to 105%. Too strong emission beyond 105% might trigger certain amps into a protective shutdown mode hence not usable at all.)

Can all tubes out of factory simply have 100% spot on full emission, since tubes are produced in modern industrial factories? No. This is NOT possible. The electron emission coatings on the tube plate, by nature, are live and cannot be 100% consistent to be of the exact same value. It is not technically possible for tube factories to have tubes produced ONLY with 100% spot on emission.

Chinese National Standard (GB) allows 845 tube emission as low as 70% of full emission or up towards 115% to be still considered Factory QC Pass. Such a wide range of 70% to 115% tolerance is to reduce production waste during the bygone era when tubes were widely used in electronics. Today high end tubes are luxury items for affluent audiophiles. We simply do not think 70% is still considered acceptable for the factory price these high end tubes fetch for.

2. We have years of experience with tube amps and will select the most suitable tubes for you.

Although we do not know ALL amps on the market, our decades of experience with tube amps have allowed us to know many potential pitfalls. We ask you to fill in your amp make and model when placing your order, then we select our known best suitable tubes for your setup. This cannot be done by vendors who simply entice internet shoppers with low prices and ‘pass on factory boxes’.

3. We DEFINE, SCREEN, TEST and Grade tubes for the right quality.

We DEFINE our OWN purchase parameters with the tube factory to control quality outright. (SORRY – these parameters are not published anywhere as they are trade inside information only.)

We SCREEN factory inventory outright by requesting factory to use the same test equipment as ours, on top of the industrial scale testers used on the tube factory production line.

We TEST all tubes we receive from factory ourselves, one by one, to confirm factory test results at our own facility.

We GRADE all tubes AFTER our own testing.

For those tubes meeting our Top 10% Best Grade parameters (after our own testing) are offered for premium price, matching to their top quality, to those customers who value quality over cheap price.

For those tubes NOT meeting our Top 10% Best Grade parameters, they are downgraded to Factory QC Pass grade and consequently sold for lower price (matching to their corresponding quality). Keep in mind that our downgraded ‘Factory QC Pass’ tubes were already screened outright from the factory inventory pool before shipping out of factory door, and inherently of higher specifications than the overall ‘Factory Pass’ tubes that are offered all over internet at cheap prices.

Among those downgraded by us to Factory QC Pass, inevitability small portion of tubes are considered ‘rejects’ by our standard, even though tube factory considers them ‘Factory QC Pass’ and shipped to us. These rejects will be returned to tube factory to claim factory warranty by us, and save our customers from the downfall experience.

In summary:

  • We offer top 10% Best Grade tubes at price matching to their quality.
  • We sell HIGH Quality. We do not just sell cheap prices for whatever quality, like many vendors on internet do.

We hope these reasons above will help you with confidence in purchasing with us.

Happy tube shopping.

P.S. The above reasons apply to other ‘Top 10% Best Grade’ tubes such as Linlai Global Western Electric Replica WE845 and other 845 varieties etc.

Why buy Elite E-300B Best Grade from Grant Fidelity?

‘Why buy Top 10% Best Grade tubes from you? There are cheaper price on internet!”

A few top reasons:

  1. Our Top grade tubes have STRONG emission capacity = LONGER tube useful life. (For example: Our top grade Elite E-300B tubes start with minimum 92% full emission up to 108%. Too strong emission beyond 108% might trigger certain amps into a protective shutdown mode hence not usable at all.)

Can all tubes out of factory simply have 100% spot on full emission, since tubes are produced in modern industrial factories? No. This is NOT possible. The electron emission coatings on the tube plate, by nature, are live and cannot be 100% consistent to be of the exact same value. It is not technically possible for tube factories to have tubes produced ONLY with 100% spot on emission.

Chinese National Standard (GB) allows 300B tube emission as low as 60-65% of full emission or up towards 120% to be still considered Factory QC Pass. Such a wide range of 60% to 120% tolerance is to reduce production waste during the bygone era when tubes were widely used in electronics. Today high end tubes are luxury items for affluent audiophiles. We simply do not think 60% is still considered acceptable for the factory price these high end tubes fetch for.

Linlai Global E-845 vs. Psvane ACME 845: ‘almost immediately sense the superiority of the Elites’

Received from customer James H. via email:

“When looking for a review of the Linlai Elite E-845, I could not find anyone who was able to compare it to the Psvane Acme 845, which is the tube’s nearest competitor….

I have the Line Magnetic 845 Premium which uses a pair of 845’s & 300B’s. I will say that the Linlai (Global) Elite E-845s have taken a very long time to sound good for me. It took about 75 hours for me to begin to like them. I do like them quite a bit now after about 100 hours.

I also have a pair of Psvane Acme 845s… which will be up for sale very soon. I did not really have to A/B the Acme’s with the Elite’s to almost immediately sense the superiority of the Elites. The Acme’s were veiled, cloudy, dark, reticent, and very much stuck in the speaker box compared to the Linlai Elite E-845s which have the opposite traits. The Linlai Elite E-845s are just in an altogether different league than the Psvane Acme 845s.
