      Well guys, my amp is completely quiet. The culprits are listed below.

      C9 - .47
      C209 - .47
      C207 - E.C. 10u/25v
      C211 - E.C. 10u/25v
      C208 - .022

      The E.C. caps are most likely the cause of most of this. I missed those when replacing the electrolytic. The amp is as quiet as a mouse and now will burn it in for a while and see what happens...
      Many thanks guys, will be back- I have to replace the factory mod of the diode network which was put in as a field notice to protect against speaker current when removing the speaker. Someone did a botch job of this one.

      Happy New Year and thanks again
      Ron
