I've a few NOS 815s myself, and have periodically thought how
cute/cool a push pull amp would be using one for the output (but then
again I don't like the overload characteristics of a SE amp for
guitar, and want more bang -watts- for my buck.)


I'm interested why you don't like the overload characteristic of SE class a
for guitar. How would you describe the sound? I made a 60 watt SE Class and
and quite like the tone, I have an attenuator though at 15 wattts output.

Hi Geoff,

Ah jeez, I slipped and let one of my opinions out!
;-)

I guess I prefer symetrical to asymetrical clipping (one
over-simplified way of describing typical SE vs. push-pull amp
clipping), I'd call it (subjectively) 'softer', or 'rounder'; also,
bass definition remains intact. SE output amp clipping is more like
preamp stage clipping, which of course is 'fine' too, just different,
a matter of taste (plenty of people like little SE guitar amp designs,
i.e. Univalves, Fender Champs etc.)

I
think the sound is not too modern though. I used a T-1000 triode.

Not modern? Like before Class B was invented? ;-)

Your SE T-1000 must be a joy to behold(!); no doubt there's plenty of
low end available for a little EQ boost to recover when clipped...
plus depending on your output tranny wind (and the freq response of
your speaker(s)) maybe some of the excessive 'bite' (IMO) when an SE
amp is clipped isn't there...

But as an 'Efficiency Cop' I'd arrest you for throwing away hundreds
of watts for just a few! ;-)
