I got this Sony TFM-C650W cheap on eBay because the clock was stopped. It was severely yellowed from UV exposure and I restored the case using Salon Care 40.
It is a very well built clock radio with lots of bits of foam and velvet tape to prevent any plastic on plastic contact that could cause noise. The wiring was all meticulously routed, secured and tied. The alarm dial has a lamp that lights when the alarm is set. The radio dial lights when the radio is turned on manually, but not when alarm is sounding or when using the sleep timer.
This model has a seconds wheel that is connected to the motor gearbox. This feature is cool, but adds complexity and serves no real practical purpose. It is a Copal GC-1379 movement made in 1974. The old alcohol bath got the clock going, but it is not perfectly silent.
The neon clock lamp was still bright enough to light the clock but I replaced it for good measure.
The alarm dial and radio dial use little green incandescent lamps. I found that "Grain of Wheat" lamps used in model railroading fit, but are a little dim. I will have to crack clock open in the future and check the voltage for the lamps with a multimeter.
