Help with Repair Carver C-1000 Receiver

Post by dbclocks » Sun Aug 03, 2014 5:55 pm


I would appreciate some assistance in my efforts to repair a Carver C-1000 Receiver. Someone worked on the receiver previously without success and I told a friend I would take a look. A schematic doesn't appear to be available but if someone has it and would like to share? Also, it appears two transistors, Q220 & 221 were replaced and possibly substituded with a different part. I would like to make sure the parts are correct, The part# installed is IRFZ44 for both locations. Also, what are the correct values for resistors R247 & R255 which are connected to Q220. Thanks
Q220, Q221, R247 & R255 located on left side of Amp PCB.

Sorry no one has gotten back to you on this. There are no schematics available for that unit; it's usually considered to be a boat anchor if anything goes wrong...

You might try Rolland at HiTech Electronics in Oregon....

I couldn't find a service manual or schematic, either.

Interesting that it's a FET amp- unique among Carver?

IME gate drive resistors are around 5-30 ohms, but I don't have experience with FET audio amps. The gate resistors control both turn-on and turn-off times. I'd guess in a linear application, the min turn-on is more important. Probably better to err on the side of too big! Minimal wattage.

Good luck! I always liked those C-1000's foreshadowed Sunfire styling.

I'd check with Bill... He is one of the very few that might be able to help on this one.
It was built BY Sunfire FOR Carver....

I've asked Bill about these before, pretty much like Rabbit said, boat anchor if it breaks. I know Bill won't work on it anyway, maybe Rolland at Hi-Tech?? :-k :-k
