- [[Linlai™ Global] E-6SN7 with Cary SLP-05 Pre:](https://premiumvacuumtubes.com/linlai-global-e-6sn7-with-cary-slp-05-pre/review/): Below is review submitted by professional reviewer Robert Grossman (with EnjoytheMusic.com e-zine): “Larger tubes produce a bigger sound; premium tubes create a higher-quality sound… I’ve been using LinLai tubes in several amps and preamps over the past five years. I offer some perspectives and listening experiences after recently returning to test and hearing the stock Electro-Harmonix 6SN7 tubes in the Cary SLP-05 preamplifier in comparison to the LinLai Global E-6SN7 tubes. When I purchased the Cary preamplifier about six months ago, I initially burned it in with the stock Electro-Harmonix tubes for about 200 hours. Upon hearing the beautiful, articulate […]

I have around 30 6SN7’S and CV181-Z’S old and new. I also have a pair of Psvane Summit 6SN7‘S. The Psvanes are louzy sounding, very scratchy. The best sounding tube’s that I have are the Shuguang CV181-Z’S. The amp that I using with your tubes is a 300B single ended class A amp I built about eight months ago. It’s number eleven […]
- [Shipping from US Warehouse now available!](https://premiumvacuumtubes.com/shipping-from-us-warehouse-now-available/uncategorized/): 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.

- [Psvane Tubes - What Now?](https://premiumvacuumtubes.com/psvane-tubes-what-now/recent-news/): We get questions often about the Psvane branded tubes we used to carry. Here is a post with updates: The PAST: Grant Fidelity discontinued direct reselling of Psvane branded vacuum tubes in 2021 due to then declining measurements of the Psvane tubes we received, and no agreement could be reached then with the Psvane factory management. We are further pressured to drop a competitor’s line of products which in fact showed superior measurements than Psvane’s. Grant Fidelity opted for product quality and business independence hence all Psvane inventory were returned to factory in Feb 2021. (Rumor said that Psvane factory […]

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 […]

- [Treasure 6SN7SE Globe: 'I got the chills from this thing'](https://premiumvacuumtubes.com/treasure-6sn7se-globe-i-got-the-chills-from-this-thing/review/): Feedback received from customer Noah via email: “Hey there, I just received a Treasure Globe  6SN7-SE I dropped it in my (Schiit) LYR+ / BIFROST and I’ve been listening to it on my (Sennheiser) HD800S. This thing is mind blowing – thanks for selling such a great tube in Canada. I got the chills from this thing. It completely evens out the tone of these headphones while still keeping a massive soundstage. I have been using them for every genre and it all sounds good, as long as it was mastered well.  I’m going to have to get more spares . . .  “
- [Push pull amplifier - tube troubleshooting](https://premiumvacuumtubes.com/push-pull-amp-tube-troubleshooting/faq/): Below are procedures that customer needs to complete to identify faulty tube, before submitting a warranty request: For Push Pull tube amps – 2 power tubes (either EL34 or KT88 – these are the most commonly used power tubes in push pull amps are used per channel.

- [A floating piece of glass inside the tube - What is it?](https://premiumvacuumtubes.com/floating-glass-piece-inside-tube/faq/): If you have been playing with vacuum tubes long enough, you might have run into a situation that a new tube, shipped from a vendor, arrived with a piece of floating glass inside (see reference picture below). What is it? Where does it come from? Is the tube damaged beyond useful?   Here is the answer: This piece of floating glass is a broken-off piece from the tube filament glass stem. See picture below showing where it is exactly broken off from.   2. This broken piece is often resulted from the heavy filament structure in vibrating motion during shipping […]
- [Customer feedback on GF Premium Tubes:](https://premiumvacuumtubes.com/customer-feedback-on-gf-premium-tubes/review/845-t-feedback/): Here is an email feedback we received from customer Thomas L about his personal experience of buying from Chinese vendors vs. Grant Fidelity: “Hi Rachel,   Just thought I’d give you a little feedback with my recent purchase.     Your tubes are expensive (adding in all the fees and shipping).  I think you would agree as well, although you may argue nothing is cheap with this Audiophile hobby, which I would agree as well. With my recent purchases, I think it was pushing around $2000 CAD.  This was for 5 845s, and two pairs of 300Bs.  Honestly, I had been […]
- [Psvane or Linlai™?  ... Make an informed choice](https://premiumvacuumtubes.com/psvane-or-linlai-make-an-informed-choice/guide/): (The post below has been updated in Dec 2025.) We have received so many inquires lately from customers asking us to help them to make a choice between the two tube brands out of China. So here is a summary of our take – OBJECTIVELY: High end product design need vision and dedication. Psvane had a track record of pumping out a few series of high end tubes for the worldwide audiophile upgrade market, since they initially launched ‘Treasure black bottle’ tube series back in 2008 till the recent ACME series. That original Psvane design team includes the same key […]
- [Which 845 tubes to get: The popular upgrade path for Line Magnetic LM-518IA tube amp](https://premiumvacuumtubes.com/which-845-tubes-to-get-the-popular-upgrade-path-for-line-magnetic-lm-518ia-tube-amp/guide/): Line Magnetic LM-518IA integrated 845 tube amp is the first Chi-Fi amp that was very favorably reviewed by Stereophile back in 2015 and got onto Stereophile’s annual award list later on. It can be considered an achievement milestone for the entire Chi-Fi industry, IMHO. Before this amp become popular, most 845 amps on the market are monoblocks, which inevitably cost more to produce, more to ship and deliver, which result in less people can afford them. A well made integrated 845 tube amp has brought the retail price mark to below $5000 range. I personally think this is a major […]

- [Linlai™ Global E-6SN7 on Feliks Euforia Headphone amp: from Germany](https://premiumvacuumtubes.com/feedback-on-linlai-global-e-6sn7-in-from-germany/review/): We have just received the feedback below from Greg K from Germany! Greg owns a ‘Feliks Euforia headphone amplifier’ which came with Psvane CV181-TII as driver tubes. Read about his first impression after swapping to [Linlai™ Global] E-6SN7 for 26hrs – it might help those who wish to know how the E-6SN7 compared to Psvane tubes: (note: Linlai tubes full burn-in will take approximately 100hrs) “I have now burned in the tubes for a good 26 hours so far.And on the Feliks Euforia, where the Psvane CV181-TII were before, a lot has happened. I listened with the Audeze Lcd 2 […]
- [Is the 'Top 10% Best of Best Grade' worth the money?](https://premiumvacuumtubes.com/is-the-top-10-best-of-best-grade-worth-the-money/guide/): You may have noticed that our tube offerings are priced to different gradings – the best, also the most expensive, grade is ‘Top 10% Best of Best Grade’ at a price premium over typical ‘factory QC pass grade’. Is the ‘Top 10% Best of Best Grade’ worth the money? What are you paying for the best grade? Tubes, like most bulk commodities, are graded according to their tested parameters from lab equipment. Although vacuum tubes are industrial products, they are not cookie-cutting universal exactly the same when rolling off the production line. Consider tubes like premium coffee beans: They are […]
- [Can your 6SN7 replace my 6SN7GT, 6SN7GTA, 6SN7GTB?](https://premiumvacuumtubes.com/can-your-6sn7-replace-my-6sn7gt-6sn7gta-6sn7gtb/review/cv181-z-6sn7/): We sometimes receive amp owners question about tube substitute related to 6SN7. Here is a short summary: GT stands for ‘Glass Tube’. GTA is an enhanced version of original GT version – to allow higher plate dissipation than the GT version. GTB is variant of GTA, with a heater warmer control to further enhance reliability when this tube was used in TVs. Very early 6SN7 tubes can handle max 300V. Today’s new production 6SN7 tubes can handle max 450V. In short, new production 6SN7 can replace your old 6SN7 without frying the tubes. But you should not use a NOS […]

- [6SN7SE Globe Tube Tips - 'You Raise Me Up'](https://premiumvacuumtubes.com/6sn7se-globe-tube-tips-you-raise-me-up/review/cv181-z-6sn7/): Some amps have preamp 6SN7 tubes placed in a very tight real estate – i.e. two tubes are placed very closely to each other so the new high end 6SN7 with curved larger / wider glass enclosure cannot fit in side by side. A customer from Europe recently told me his solution and I think it is worthwhile to share! That is – use a socket saver to raise one of the tubes up! Just google ‘8 pin socket saver’ (not ‘socket adapter’ which may change pin layout connections) and make sure to purchase from a reputable audio parts vendor. […]

'real keepers!'](https://premiumvacuumtubes.com/hear-what-the-cable-pro-said-about-linlai-global-e-845-real-keepers/recent-news/): Eric D. from France is an industry pro specialized in ultra high end cabling. His audition skills are professional and field proven, and here is what he said about after owning a pair of [Linlai™ Global] E-845 top grade tubes: “The Linlai E-845s are very nicely built. You can tell by looking insidethe glass tube that they are manufactured with care. When brand new,they performed nicely, but it was after about 120 to 150 hours that theyreally came alive. They really need that burn-in time to reveal theirfull potential. I’m not the patient type, but this time I was glad […]

Ayllon spent time with both tubes on his ultra high end Lampizator Big 7 Mk1 Digital to Analog Converter for ‘An Aural Indulgence‘ “If vacuum tubes were wine, the Linlai would be a sophisticated French red Bordeaux blend from the Left Bank of the river Garrone in Bordeaux, France, while the ACME would be a top shelf Cabernet Sauvignon from California’s Napa Valley served in posh steakhouses.  Don’t get me wrong; both the Linlai E-300B and the Psvane ACME 300B render rich, well-balanced presentations, and if I were not making conscious A to B comparisons, it would […]
- [I got a USPS tracking number.... now what.. why isn't it moving?](https://premiumvacuumtubes.com/i-got-a-usps-tracking-number-now-what/recent-news/): For tube orders from USA customers, we sometimes use Canadian domestic courier service to ship to the border of Alberta/Montana, then customs brokers clear the parcels through US Customs into the USA for final delivery by USPS. Once the parcels entered the USA (AFTER customs clearance and released by US Customs), the USPS tracking number will become live tracking on www.usps.com, and the journey starts from a small town called Sweet Grass, Montana. Don’t jump when you see your order was shipped from Montana, not from Canada. It’s just cross-border paperwork to get on USPS shipping network. In the above […]

- [What you should know about high voltage tubes such as 845, 211 and 805](https://premiumvacuumtubes.com/what-you-should-know-about-high-voltage-tubes-such-as-845-211-and-805/faq/): Some precautions about using high voltage power tubes: Unlike other vacuum tubes such as KT88 or EL34, which typically run at 450V plate voltage, high voltage power tubes such as 845, 805 and 211 run at plate voltage 900V or even higher depending on your amp design. Due to the high voltage in the circuit, biasing an 845 / 805 or 211 amp improperly may expose you to lethal high voltage causing instant death.

But over years, the factory’s lack of quality screening has flooded market with mixed quality. We (Grant Fidelity) no longer carry them as the ‘selection’ cost is simply too high and performance varies too much.  WE Plus series is the latest release before Shuguang factory went into relocation and ceased production in 2020 till further notice. From our own evaluation, the sound of this series is much better […]

LINLAI is a trademark belong to a NEW tube factory in China – formed by a team of engineers who exit Psvane in 2019.

The tube(s) are doing well. No issues seen and I have about 10 hours on them so far.I gotta say “wow!” these are deadly quiet, extremely dark but not in a soupy muddled way, they are still very dynamic but the silence is incredible. I am really enjoying these so far and I am sure that they will continue to develop.”  
- [Type 50 tube "if you like the sound of the old triodes go for Grant Fidelity (type 50)"](https://premiumvacuumtubes.com/6900-2/review/): Read review by long time Type 50 tube lover Rob from Netherlands: Conclusion:Winners are Grant Fidelity and EML. I would put my money on these. You get new tubes, with warranty. If you like the sound of the old triodes go for Grant Fidelity, if you do favor a bit more modern sound, EML would be your choice. Comparing the Grand Fidelity 50 to the originals, the originals will set you back a heap of money for used pairs, whilst difference in sound will be subtle. You get the same character for far less money, and new. As a runner up I mention […]

Replacing the Psvane T-IIs, I find the sound is more articulate / better organized / more coherent / less homogenized. Appears as if the noise floor has been lowered, better low level info retrieval. Better bass, too. My comments should be taken with a grain of salt, as I did not do an A-B comparison, and there was about a week’s gap in listening, so I […]

Put the new tubes in and turn on, first 10 mins, comparing to Psvane 12AX7-TII…the new super tube has lower noise floor, sound is more dense and transparent, bass is deeper and better bass layering. Sound is richer and much more transparent. I’m playing internet FM radio and it is finally making music now. Before that, I can hear it is digital and an inferior sound, but not anymore. I’m less critical of my internet FM radio through streamer and enjoying it. Vocals […]

In a high resolution system, especially of the low-to-no negative-feedback persuasion, these Shuguang globe 6SN7-SE bottles are the state of the new-wave-of-valve-production (NWOVP). So far Shuguang have not put a foot wrong and we can hope they continue to innovate new versions of those classic valves we all love.” Read the full review here.

It is a replica of NOS Phico black plate 5U4G rectifier, but maintained a very friendly price tag. Rectifier tube is probably the most ‘consumed’ tube on a tube rectified amplifier. It will need to be replaced more frequently than a power tube over time, so reliability and price are both sensitive factors for tube amp owners. Now Psvane is offering a new option for tube amp owners who are not only cost conscious, but also sound driven. Click here to […]

This is another addition to the series and quality carefully selected by Grant Fidelity for worldwide audiophiles and music lovers. Reviewer Mark Wheeler from TNT-Audio said: “I have not heard a better current production 6SL7 from any manufacturer. NOS samples are too inconsistent to recommend.

What type equipment is used in making vacuum tubes? Instead of diving into technicality and confuse everyone, I have a short answer here – vacuum […]
