Acting on the premise that Eric picked an eminently qualified power tube for the Ultimate, I have been exploring my stash of 6N7 tubes (using an ECC31 to 6SN7 adapter).
These tubes sound very good in the Ultimate. Here is today's roll - a Neotron (aka Visseaux) 6N7GT:
Please notice the French sculptural artwork inside the tube - it sounds as good as it looks!
15 Ultimaters since April of this year is an achievement. I know of 2 other owners but don't know their names. One was the first to get the Junior Wooden 6Y6G amp before it even became known as Ultimate. The other, Eric modify the 6bx7 amp into Ultimate for him.
6K6GT is a variant of 6V6GT. It's a Haltron brand and that's good. I would buy it but it's stated there that the seller won't ship to Australia. The price of EUR 9.35 is cheap.
The Haltron brand was part of the British company Hall Electric company that distributed valves and components in the UK.
They tended to buy stock from all European factories as well as Japan.They had a contract to supply the ministry of defence and so had had test facilities to supply to MOD standard.
I like APOS and have bought gear from them, but their statement frum the link you provided that it is a "substantial upgrade from standard NOS tubes" seems a bit much, even as marketing hype. Looking forward to your further impressions.
I understand the views.
What I can say at the moment is that it plays quite linear, I suspect that the EL81 Ultron adds to it and the Ultimate is fine.
Tonight I'll try some more output tubes to see if it stays or changes.
Gave the tube another night together with the Ultrons to get more hours on it.
More impressions to come to see which driver tube it might conqurate with, off the top of my head I'd say it's Siemens where the tube shares the chair, but I'm still figuring that out.
For a New Stock it makes an excellent impression and job so far.

Yes , but I haven't tried it yet, waiting until my Ultimate has over 200 hrs, at around 130hrs at the moment and loving these Svetlana KT88's , such textured base, hard to resist
This is for all Ultimaters. You might as well learn about 6y6, 6v6, 6f6, 6w6, 6k6 as these are your bread and butter power tubes and some of them can even be used as driver tubes.
