This iconic late ’60s GE clock radio came to the shop with loud, low humming when turned on and no radio reception. That’s a familiar problem! Time for new capacitors. This particular used a 100 uF main filter and several 200-400 uF secondary filter capacitors around the boards, along with three electrolytic coupling capacitors in the signal chain. They were very tired and as shown by the hum had started to short out; if the radio continued to be run with the loud hum it could have been badly damaged so it came in just in time. Some new components later, she’s good as new and sounds surprisingly good for such a small radio. There’s a mystery switch inside, too – do you know what it might control?

This Silvertone 1827 with an artistic finish came to the shop for an overhaul. It had been kept running for about two decades by its original owner before being put aside, and ended up getting all new capacitors and a new #85 tube which had shorted out. It had been well loved as the quality of the historical repairs was very high, and it had all Silvertone brand tubes, so could even have been dealer-maintained at Sears its whole life. After component replacement and an alignment, it really sings and has spot-on dial tracking and even pulled in a shortwave station.

This Bose® 901 Series II Active Equalizer is a part of Rain City Audio’s parts stock and got a full rebuild with upgraded parts and complete and comprehensive testing. All transistors, resistors, film and electrolytic capacitors were replaced, a new neon bulb added, and the controls cleaned and lubricated. This very detailed repair walkthrough has photos showing the drifted carbon composition resistors which can throw off the equalizer’s curve even if all the capacitors have been replaced.

This little 1959 companion transistor radio came through the shop for a tune-up. It, like most of the others, was in good shape except for the capacitors being dried out and no longer performing their functions. One was badly cracked, even, but the radio still worked after a fashion. With new parts installed it’s good as new. Keep reading for detailed photos of the tear-down and replacement parts.

This 1958 Zenith Royal 500, an early 8-transistor portable AM radio, came into my shop for a complete overhaul. I replaced several badly out of spec capacitors, added some insulation to correct a short circuit in two of the batteries and gave it an alignment. This is a perfect radio to take to the beach or the park while listening to a ball game, just like they’d have done back then. Many tear-down photos inside!
This Bose 901 Series II Active Equalizer got a full overhaul in the shop with all new capacitors, resistors, transistors and silicon diodes. After a thorough control cleaning, it sounds absolutely fantastic once again and should last for a long time to come.
