It's a two channel 50 watt class-a el34 amp. 50 watts seems like a lot
for el34s. Sounds pretty good though but has somewhat of a transistor
like sound to it. Ever hear of it?



50 watts is achieveable with one pair of EL34s, but it won't certainly
be class A .
I'd say they're biased low, near B.

Don't they mean a 2 x 25 watts design? EL34 PP in A will deliver close
to 15 watts in A entirely, above that (and with a lower than rated
load) it'll shift towards AB.
You'll have to measure the anode voltage and current to determine the
operation point, as well as knowing the Ra-a- of the output
transformer with the rated load.

What's a "transistor sound" like to you?
