RE: What capacitors to buy to refurbish old RCA amp?

There is global feedback here, it is just taken from the primary of the output transformer instead of the secondary

I noticed now but I have never seen the GNFB come off the plate winding like that.I have seen local FB implemented like that.
.Most RCA amps did have two 5R4s,at my RCA theater amps do with 807s.

Here is the thing,the Schotkeys sound like a tube rectifier without the loss and they are quiet.I would work with Eli a bit on the 6SL7 driver stage because you can make a lot better amp with a more suitable driver stage.The 6SL7 is ok because your driving pure pentode but being you have four 807s and regulated screens,give those 807s some extra wheaties.
