Re: Add an HT Fuse?
I'd be interested in commentary regarding fusing the rectified DC line vs. both HT legs of the secondary (AC).

Re: Does anyone recognize this amp design?
I love the "mystery switches". No other fonts were available, maybe, huh?

Re: My take on a 2nd Gen ODS
Thanks! Been trying to pass a 3mm kidney stone for the past three weeks now. Tomorrow morning I'm having shockwave lithotripsy done to try to smash up the 7mm stone that's still up in my left kidney. I've been dealing with stones for about four years now. I've changed my diet but they run in the fa...

Re: SSS #002 REDRAW DRAFT
Just noticing this traffic. Is my "redraw" draft correct, then, with respect to the Reverb input NFB? It looks like it is to me. Best.

Don't buy someone else's mistakes if you're just starting out. Start fresh.

Re: Hurrah, a new transformer.
An amp that's "burnt three Weber PTs" likely has a problem that needs sorting. Good recommendation to use fuses or proper bulb limiter to protect and diagnose the circuit.

"Second stage molecular realignment."
Hmmm.
(Buys fuses at hardware store for $2.)

Re: Stereo Ampifier?
No 'half-wave" -- Output of each PI triode is a full wave, just that they have inverted relationship; and it's the power stage that due to bias etc that divides the work into AB push-pull .. Good point. So then parallel SE output stages from each side of a PI tube would then cancel each other out. ...

Re: Stereo Ampifier?
I'm not sure I understand the design goal. Are you after a wet/dry rig with one side doing reverb and the other dry signal? If the goal is reverb-only on one side rather than reverb mixed with the "original" guitar signal, I think that's only possible with two separate channels, whether that's usin...

Re: Stereo Ampifier?
My understanding is a stereo signal required two outputs, one for "right" and one for "left". A single speaker cannot, by definition, deliver a stereo image. The half wave feed to a speaker seems impossible. Perhaps an alternative would be running two parallel PP output stages, but then how do I inj...

Stereo Ampifier?
Can you give me an example of a TRUE STEREO guitar amplifier? Seems most are dual mono. Not an earth-shattering contemplation, but I have an idea bouncing around. Can you feed a speaker a half-wave signal?
