Reduce signal from preamp.

(1/3) > >>

flester:
I have built amp with a starved plate 12au7 preamp feeding a solid-state power amp module. There's a 100k audio pot controlling the signal going to the power amp. Whats the best way to pad the input to the power amp? A resistor in series somewhere?

Well how about a schematic?

Sorry, here you go. It was late when I posted

I'm running it at 12 v. The preamp and the power amp work fine when tested seperately.
