Fisher Statesman console
Posted: Sun Jul 24, 2022 6:43 pm
Hi-Fi Mogul was recently contacted by someone seeking repair help for a Fisher console, and asked me if I wanted to take on the
tuner and amp repair. What she has is a Fisher Statesman console, Model S-70 with the SA-100 amplifier that she acquired at an estate auction for $200. Hi-Fi Mogul took on the task of returning the Garrard changer to operational status and I picked up the tuner and amp a week or so later. A quick visual; inspection showed no burned resistors, exploded caps or transformers oozing anything. Testing the tubes showed that ~70% were still good so after performing a continuity test on the transformers I ordered replacement tubes and put in an order for capacitors and a bridge rectifier for the filament supply with Mouser electronics. I started with the amplifier and after replacing the tubes and capacitors I powered it up and set the bias voltage per factory specs. I had a bit of trouble with one channel so I cleaned all the tube pins and sockets and re-soldered a few tube pin connections. This solved the problem, so I moved on to the tuner re-cap, playing music through the amp while doing the work. After re-stuffing 2 of the electrolytic cans and replacing the filament supply rectifier, I carefully disconnected the parts from the others and mounted new caps underneath the chassis. I connected the amp and turned everything on and after the tubes warmed up I was able to tune stations on AM and FM and connected a Bluetooth receiver to the AUX input. So satisfied that it would work, I proceeded to replace the small electrolytic caps and all of the brown capacitors. Upon completion I cleaned all of the tube pins and sockets, removed dust from the chassis and polished up the tube shields and carefully lubed the tuner string pulleys. After that all of the pots were cleaned and lubricated and once the cleaner dried I moved the tuner and amp to my living room, connected the amp to my JBL Lancer 77s and connected a turntable. A RCA Red Seal recording of Beethoven's 6th Symphony seemed appropriate and that kicked of a 4 hour set of music to get everything up to temperature and see if anything started making noise or causing distortion. The sound was everything I expected from Fisher equipment, so the owner was contacted and I re-installed everything into the pristine cabinet yesterday. I fabricated a bracket to mount a 3 inch fan to help cool the amp and mounted it on the cabinet. After everything was re-connected, we turned it on and she was amazed at the quality of the sound and excited to spend time playing records after waiting several years to find someone to repair it. This is the fourth Fisher that I have worked on including my Dad's 500B that I still have, a Custom Electra III and a 400 and this one impressed me as much as the others.
