6J5 Shootout - which one's best?

[Rodango]

The early '50s Soviet Metal-base mil-spec 6S2S (6C2C) gets my nod.

Other opinions?

Has an authoritative shootout ever been done?

I have no opion in this matter, but I like the 6J5 as they are closely related to 6SN7 but costs less than half price.

I used Westinghouse JAN 6J5s in a gain stage. These worked out just fine: no microphonics, and linearity and gain as advertised.

How about a good old L63.......

I like the 7N7 as an alternative. Like a 6SN7/6J5, dual section... but with LESS Cgp (higher bandwidth) and cost a LOT less, being a loktal-base tube...

Gordon.

I've tried the Sylvania 6J5GT and Mullard CV1932
but the pair of Hytron labelled Mullard 6P5GTs
leaves the others in the dust 8^D.
Slightly lower gain but much better sound
makes the others sound harsh in comparison.
Maybe it's the round plates - I don't know.
I use them in my DIY SE KT66/6L6G amp.
Paired with Tungsol Re-issue 6L6Gs in the coke bottles
brings everything into my living room.
Paired with the Genelex KT66s and
you are at the concert front center.

I think I have a new favorite. The GEC CV-1067. Has anyone else tried them?

I used to have boxes of these types, but I'm gradually selling them off on ebay since I use DHT small tubes now. But these 6J5 types remain one of the great bargains in audio. Standouts are, in my opinion

6P5G
6P5GT
2C22/7193
CV1932

But then there are all the following:
Pinnacle 6J5GT - Morgan loved this in his Valve Amplifiers - he tested it as ultra low distortion
6C5G - very interesting one this, especially the Fivre. Has a mesh screen
6J5G - loads of interesting and good sounding ones here - round anodes, flat anodes etc. Very good value, cool ST shape
6L6G - not to be overlooked - similar anode structure to the wonderful 6P5GT, cool ST shape
