Default What is it?

Awesome, 26 Watts from a pair of 6V6s is pretty impressive!-


** Fraid it is quite commonplace.

Fender amps like this example from 1963 did the same.

Note the use of -35V grid bias.



Thanx for that link Phil. I'm always amazed at how these guitar pickers
keep their stuff running with the OP section at these gross
overvoltages.


** The printed numbers are at idle conditions - at full output the HT
falls by about 20%.


JJ claims to have a better 6V6GT version, see it here-

Has anyone tried JJ?


** Yep.

JJ have cheated - the plates of their " 6V6S " are identical to Sovtek
5881s so the available dissipation is way more. The heater / cathode
structure is modified to give the right numbers for a 6V6.

While this makes the tube ideal for use in amps like Fender Delux Revebs
that really " push the envelope" it sets up nasty a future problem if the
tube ever goes out of production.
