Electro Brand 4610 AM FM Clock Radio A Look Inside

[@VintageElectronicsGeek]

Hey Jerry, looking at the data sheet for the clock driver....pin1 (closes to the display) is for AM (morning) & 10 seconds; pin 28 (closes to the transformer) is for 24 hour time setting....these to pins are used together when the clock offers a 24 hour setting, such as in the Europe market. Reading the data sheet on this chip does state it is capable of being used at 50/60 hz reference. This appears to be a Swiss Army Knife kinda chip and apparently is used many clock designs. Hope that helps some. Thanks for showing the guts. ~Jack, VEG

That’s interesting Jack, I guess the design must have had those two pins going to traces on the PCB for other markets and the fix was to bend the legs. Thanks for the information and for stopping by my cool radio friend. 👍❤️📻

Old style radio chip with variable capacitor. I wonder if today's radio alarm clocks all use DSP radio chips. It appears that none of them have the tuning knob but just autoscan and preset memories.

The newer clock radios have software controlled microchips and cell phone chargers and other useless things. The radio is almost an afterthought, that’s why I use a 90’s GE clock radio. They sure don’t make them like they use too. Thanks for stopping by. 😎👍❤️📻
