RCA grounds are 10 and 8 respectivly and are made with 10 ohm resistors. Yes, you need to make sure 9 goes back to the quad cap ground. Also make sure the .02uF "3 legged cap" is connected to quad cap ground as well. Do you have the 1K carbon resistors shown between 22,23 & 1,2 actually mounted on the el34 tube sockets using pins 5 & 6?Does your amp hum (or do whatever it is you call feedback) with RCA shorting plugs in place? What work was done to cause this condition?
