Title: Post PI Master Volume Coupling Cap
Post by: scstill on March 02, 2021, 01:10:53 pm

Will it matter if the coupling cap is before or after the Master Volume?
I can't remember where I got this idea for MV, any suggestion?

Cap must be before the MV.

i don't think a couple hundred volts dc going through a ~1/4w pot to ground is a great idea, so as stated above you want the cap before it
