1969 GE Model C2504B Transistor Clock-Radio Repair

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? Read more for more photos of the repair.

1959 Magnavox AM-80 Companion Transistor Radio

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.

1958 Zenith Royal 500 Portable Transistor Radio Repair

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!
