Thank you all for responding to my posts. it is very much appreciated.

I think my 6v6 family is large enough that i will not be able to know them all.


Thank you

FWIW I finally tried some NOS 6EZ5 and 6EY6 tubes I bought a few years back in a new build...and as was said they pull waaay more current than a 6V6 so a rebias is definitely in order i.e. read 18V across a 250 ohm shared cathode resistor in a PP amp with a 6V6's installed and got 24V with a 6EZ5 or 6EY6.

I hope this is not hijacking the thread - I wanted to ask the '6V6 gurus' a question about this tube. I am looking to use it in a 'heavy driver' stage. 6V6 attracts me because of the beautiful triode curves and low Rp.

What's the maximum safe working voltage for this tube? I know what the spec sheets say obviously - but could I get away with say 15mA CCS per side in a push - pull choke loaded LTP with B+ at 500-525V, but the 6V6 plate idling at 300V? I would be using the Electroharmonix GT version.

How are you going to pull 200V of drop through a plate choke with only 7.5mA per side? I doubt your plate choke has 50K-Ohm of copper in it.

Fender guitar amplifiers often run 6V6 over 400V all night long. 440V is not uncommon, and 500V has been seen.

I think the 315-350V rating was both conservative and Marketing. You don't need over 250V to get full Class A power with decently low impedances. If you really want "more!", buy the bigger/costlier 6L6 or 807; that's why they exist. Ah, but Fender kept pushing the little shot-glass 6V6 and didn't find much problem.

> How are you going to pull 200V of drop

"LTP" = long tail pair?

I'd guess his tail is 200V high.

At that point I would be concerned about heater-cathode insulation breakdown.

thanks PRR, the heater cathode insulation breakdown is a very important aspect of tube design...one of the things i give serious attention to, specially at turn on when the filaments are still colds...
