Just picked up my first Carver it is a 6250. I love restoring older vacuum tube radios and some "newer" 1970s and 80's electronics. Found it at one of my local thrift stores i get my old radios from and decided for $15 that I couldn't go wrong. I put it on my test bench and now shorts or smoked components. powers on. So I am here looking for the common failure points for this unit. I have found and downloaded the service manual already. can't wait until I can get it running as a daily driver.
