Description

Updated MKII version:

Note: In this new production batch as of March 2025, we have opted to install a metal tag INSIDE the tube showing ‘GF-Select’ and serial number without no printing on the tube glass. This is to differentiate from counterfeit / knock-off’s and reduce manual handling & potential damage during glass printing process.  We have also enhanced the tube for better measurement, reliability and longevity. 

Counterfeit / Knockoff’s warning!

This GF-Select Special Edition 6SN7SE Globe shaped tube is ONLY available from this website – we have never signed up any reseller / dealer anywhere inside or outside of China, for quality control reasons. Make sure you are indeed getting our ‘GF special edition’ 6SN7 globe tubes but not a ‘knockoff ‘. Any similar looking, claimed 6SN7SE tubes on the market from any other brands / re-brands or resellers are not from us and are counterfeit /knockoff’s. https://premiumvacuumtubes.com/which-6sn7se-should-i-get/

Tube Fitting: (check on your amp before order)

The 6SN7-SE widest part is 58.5mm (2 1/3″) diameter. Assuming you need two tubes 0.5cm (about 1/4″) apart, you will need 5.85cm + 0.5 = 6.35cm (2 1/2″) from center to center of the tube sockets in order to install two tubes side by side. 

“Could this be the next best 6SN7 on the market today?” – this is no doubt the ambition in the design team’s mind when they bring this model to the market!

One very experienced distributor / dealer for ultra high end audio equipment in USA, who had the opportunity to audition this model of tube,  said: “I have so many 6SN7’s and actually like the TJ Full Music brass bottom, gold pin, ST shape 6SN7, as much as any NOS vintage tube! These globes were even better!”

Grant Fidelity has organized this current MKII Special Edition production to bring this globe shaped 6SN7 to the market for the absolute high end market.

It is a ‘Special Edition’ (SE) MKII: all previous Treasure series of tubes all have carbon coating inside to make the tube a ‘black bottle’. This SE MKII is of a see through clear glass enclosure, but in a very eye-pleasing globe shape.

In order to ensure this Special Edition MKII globe shape 6SN7 to be of the best possible quality, we actually throw away over 50% of all finished production tubes in order not to compromise on final quality. After the initial screening, the QC passing tubes are further screened for low noise, section balancing and optimal plate current etc..All Grant Fidelity screening efforts have resulted this Globe 6SN7-SE to be a very limited edition for worldwide audiophiles who demand the very best quality and they are ONLY sold direct by ourselves on this website. There are two grades available – Low noise  (A) and Driver stage (B) for different application, with the driver stage (B) grade slightly less expensive than the A grade.

As always, all warranty is carried by Grant Fidelity from Canada. Please purchase with absolute confidence.
