i'm wondering about the purpose of the two red LEDs in the Vr section of the following circuit:http://www.geocities.com/tpe123/folkurb ... ppets.html
it seems as though they replace a second 100k resistor which would turn it into a voltage divider.
additionally, how would i go about replacing the pots with a vactrol, seeing as all three lugs on the pots are used?
p.s. where is everybody? the board seems to have died lately.
The LEDs provide a voltage drop that works just like the resistor. Just another method! The Freq pot is actually a CV so you don't need a vactrol there really. Vactrolling resonance would be a bit harder.
I'm not sure - sometimes posts lapse. Invite your friends!
