Why?If I had designed that amp, it would have a B+ that is closer to 300VDC than 400VDC.
Who Knows? I Would Have Guessed He Would Design A Solid State Amp.Why?
LOL, but no, I’m serious.Who Knows? I Would Have Guessed He Would Design A Solid State Amp.
Me Too!LOL, but no, I’m serious.
Lower V+ is more preamp compression. Modern amps often have lower plate voltage.Why?
"Builders" And "Fortin" In The Same Sentence?Further to that, some builders like Fortin, Friedman, Larry and others are using PT with higher voltage taps and splitting V+ on V1 via two resistors. First, V1 via 100k plate resistors feeds a clean channel for big headroom, and the drive channel is fed by a second resistor in series (100-220k) for more compression.
It is probably what PRS do as well
I’m familiar with what various changes do, I was curious as to why he’d prefer it that way.Lower V+ is more preamp compression. Modern amps often have lower plate voltage.
P.s. I’m guessing his preference would be more for the effects on the power stage… softer, more “vintage” sounding and less odd order harmonics.Lower V+ is more preamp compression. Modern amps often have lower plate voltage.
It's a preference on a paper. My Fillmore 50H has 440v on the plates, yet it's full of harmonics and quick enough to be mistaken for a modern amp when gently boosted.P.s.

Not a fan of Mike?
Yes, but he said his preference would be to reduce B+ from 400v to 300v. All other things being equal, wouldn’t we expect a bit softer “more vintage” sounding power stage, with some reduction in odd order harmonics, with that change? Admittedly, I haven’t looked at a schematic, but have seen one for other “versions” of this circuit. And, I’m now a solid 10 years past any reading or study of that stuff….It's a preference on a paper.

I think we’re saying almost the same thing but you’re disagreeing…. Let’s forget “vintage” then as that must be what’s throwing you off. I meant, reduring the voltage would soften the power stage. Reduce punch and impact… you said “more compressed.” That’s what I’m talking about. Less punch, softer/more compressed…. I know every vintage amps isn’t that way, but was referring to the ones that are. If I wasn’t clear I guess that’s on me, but I think we’re saying the same thing.reducing the plate voltage for a more compressed tone.
