I have a Reveille line stage that I recently assembled and its been checked out at Welborne's shop. It works just fine on their bench. I am unable to eliminate the low level hum when its in my system. The CD player is grounded and I added an external strap between the CD chassis and the AC line ground but it didn't do anything. All ground connections measure zero ohms on my DVM. There are no other sources hooked up. There was no hum with the previous preamp (AE-1)so I have a baselined system that was hum free.
Any suggestions would be appreciated.
Thanks,
Dave
