Potentiometer Questions Started by norbss Yesterday at It would be great if I could put it to some use. Just thought that they may have placed a jumper at the main board somewhere to simulate the switch if they knew it would be sold it a 60 Hz land like North america. Of coarse, there is japan which is 50hz in the west and 60hz in the east. You might not need to disconnect anything, try linking pins B and C and it might work.
Datasheeet for all the information you have provided with regards to my issue. I’m assuming now all I need now is short the power to pin 25 or 26 and test it out. I cannot remember the IC id most of those old clock radio’s used.
A “1” in bit-7 will identify the alarm circuit. LMLM I went ahead and checked the pinout.

Also, for 50Hz, I think you want to tie pin 26 to ground Vssnot power pin. Or tell me what I need to buy to make it run at 60Hz? What clock IC does it use? It appears that the black ribbon cable is 4 wires and there are 5 points, one of which is your red trace line adtasheet “a”. So in 50 Hz land common “B” gets connected to “c” which is what you have now without the missing part. That’s why I’m wondering if your notations are correct.
I then purchased a step down converter so it would work and it does just fine however the time is out by 10 seconds. IIRC, there was 2 version’s of the chip. Have you checked the continuity datashewt pins A and B?
Hi Eatasheet Apart from doing some basic electrical work back in high school 13 years ago it would be safe to say that I have lost some skills and require some assistance.

On the back of the clock radio there is a place where it looks like a switch should be to allow me to change between 50 and 60 Hz. Here is the pinouts. I suspect that there may be more missing than one might think if the distributors knew that the clock would only be sold in a area of 60 Hz.
