i'd suggest you contact mick and ask him how to contact kevin covi. he was mick's us partner and is fairly quick about repairs in my experience. sorry to hear about your cabernet. is it a dual or a single?
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?
