GP-DX polar axis illuminator repair

Recommended Posts

Hi,

Does anyone know where I can find a suitable potentiometer to replace the brightness control on a GP-DX polar axis illuminator? It's an 850k ohm pot according to the text printed on it - I guess logarithmic - but it needs to be the same size as the original to fit on the PCB and I just can't find one...

If someone can tell me what this style is called it should be easy, but they come in a bewildering range of sizes and forms!

It needs replacing as a previous owner of the mount left a leaky set of batteries in it for too long.

Thanks in advance

So, if anyone one day needs to know...

I'm pretty sure it's actually a B50K 12mm radio potentiometer. About a dollar including post from Aliexpress. Will only know for sure if it fits when it arrives by China Post in a month or so.
