Thanks for the info. Any idea on how to contact either Mick or Kevin? Any email addresses or phone numbers would help. The Preamp is a Cabernet Dual.
Supratek Cabernet Preamp
Now that Supratek is out of business who can I get service from? When I turned on my system got a loud pop out of the loudspeakers but no sound. I checked the 4 amp fuse and it is good. I took the pramp out of the circuit and ran direct from the CD player and everything is fine. Something in the pre is amiss, what can I do?
