Yesterday I spent some time trying to tinker with C3 and introduce the R8. No result, same thing.
The last thing I did, I ordered 12AT6 and 50B5 on eBay, they are cheap, I got 8 NIB AT6 for 8 bucks and the 50B5 for under 5 bucks, also NIB. I wasn't able to change these as I do not have them. 50C5 I have which is exact same tube as 50B5 has a different pinout. There was something about RCA not being able to pass some safety with it and the pinout change did it. Kirk sent me some tubes but not these.

So if THIS does not work (not sure why it would but have to try, nothing else is left)....screw it, the 100K R4 seem to almost do the trick - the stations stay good and the hum goes down about 10dB.
