This is what I'm using now, I removed the original .02uf blocking cap and replaced it with the .33uf cap, so now there is only one cap on the output. I'm getting 0.6vdc on the RCA's so I guess I need that second cap after the feedback loop. Replacing the original cap with an Audyn Q4 gave a pretty good step up in clarity, not sure whether its because there is only on cap on the out , but more likely its because I replaced a 50 year old black cat cap with a modern one.I think it will sound even better when I rebuild this with all modern components. All through this I am still getting little pops and clicks through the speakers when other appliances turn on and off in the house, and a much louder crack when I turn off the power amp. Maybe its just circuit design. At the speaker terminals on my power amp I am getting essentially 0vdc, though it fluctuates a little at around 0.1-0.3mv then back down to zero briefly.Maybe my meter cant read the voltage correctly as it so low?
