Hi Guys,
Over the weekend I upgraded from a Primare Integrated amp to a Copland all tube preamp and a Rotel 1080 power amp. Since connecting it up I am getting some really funky stuff happening.
Frist I had quite a loud hum coming from the speakers when the power amp was turned on. I then cut the ground pin off the connector and tried again. The hum was now reduced to a more acceptable level (not gone, but certianly liveable).
But now when I turn the preamp on I get the same loud hum. Then, turning the preamp off does not reduce it.
I just can't figure this one......any suggestions?
Thank you in advance!
Adam.
