Philips center-tap Potentiometer

Geschreven door Ahmed Abasiry op 26. Jun 2003 07:40:35:

Hello All,
Sorry I do not speak Dutch. I hope you don't mind me posting my message in English.

I am working on restoring a Dutch made Philips radio model 844x (c. 1942-3). The volume control and the tone control in this radio are basically a potentiometer with total resistance of 0.85 Mohm. The potentiometer has a center tap dividing it into 2 segments, 0.2 Mohm and 0.65 Mohm. I believe this type of center-tap potentiometer was popular in Philips radios of this era. The potentiometer has a total of 4 pins (wiper, two ends and center-tap)

The problem is the volume control is totally worn out (reading very high resistance and unstable). The Tone control is about to quit too. I was wondering if there's a place where I can find used or new old-stock of these potentiometers.
I live in Canada and Eurpoean radios here are not very popular and almost impossible to find parts for them. I am proud of this radio since it is very rare here and would like to get it to work again and I would appreciate any help or advice to get these pots.

Thanks and Best Regards,
