I looked at Aiken's paper on negative feedback and was wondering where in the valvestate schematic is the was the "negative current feedback" loop or the circuit that creates it.. From what the explanation sounds like - it does the opposite of negative voltage feedback.. increases mids and decreases lows and highs instead of flattening the mids and accentuating the highs and lows... And Ken,, whats an LFO? I did what you said and it worked fine and the three caps in a row as well. Sounds almost exactly like the original feedback loop when its closed.. How bout if you take the signal back 2 stages instead of one? will it still be negative feedback? (sounded like it) thanks for the help.. anyone have any other interesting mods/hacks with negative feedback? (totally different subject) right now I'm trying to figure a way to get all my preamp tubes an equal supply voltage in my marshall..

sounds like - it does the opposite of negative
voltage feedback..
increases mids and decreases lows and highs instead
of flattening the mids and accentuating the highs
and lows...

And Ken,, whats an LFO? I did what you said and
it worked fine and the three caps in a row as well.
