Hello everyone.
I am looking for a compatible, if not the same, potentiometer for Yaesu G-5500. The AZ is starting to do its dance queen. Flickers between 180-270 and stabilizes after matching SatPC32 target. But swings left at that area then settles. I have already place some de-oxit on top of it (or better say, bottom). It helped somewhat but I see the need for replacing it at some point soon.
I placed a call to Yaesu Tech support and I am waiting on them to call me back. The person answering the live line though first told me that the part is not available. So I requested tech support. This system is still being sold new all over the place and the pot must be available. This same pot seems to be used in other similar Yaesu rotators, i.e., 5400.
The pot has a number written RA25Y20S B501 083 321 which matches the number I saw someone who posted a Yaesu receipt of service performed. Yaesu part number is S8101823
I have seen some on the #Bay that were listed by purchasers as compatible. I missed the chance to buy the last two:

Any help is appreciated.
I did some research and found the manufacturer.

I didn't find a supplier, but I did find a datasheet. You can probably find a replacement from a different manufacturer.
Curiously it is only rated to -10C.
