I had this several years ago. When I got it open, the pot was fine, but the fine center arm wire had broken due to fatigue. Another bad mechanical design issue in these otherwise nice rotors.

By all means, get a replacement, but if the pot is good and could be easily repaired by soldering and reinforcing mechanically the connection, you can keep the spare for when you really need it.

Good luck!! 73, Jim [email protected]

Nick,

2-3 years ago, mine failed. I called Yaesu/Vertex, and after talking them through finding it in the rotator rather than the controller, they

came up with one. Parts and shipping were "reasonable."

The 500 pot on the Yaesu g5500 elevation rotator failed. Does some on the list have a replacement part number and source preferable a USA

source?

Thanks

Nick,

Finally dug through my Yaesu receipts to get the AZ pot info from this past April. At that time, the part number was S8101678, "Pot. 500 Ohm(new). Price, including shipping, was $20.51. This pot doesn't have the wire from the wiper.

Also, while I had the azimuth rotor disassembled, I installed a thermal switch mounted against the motor windings. The "Thermal Circuit Protector, 75C" is All Electronics part number THSW-75 and was $1.00 (less shipping). When I next have to open the elevation rotor I'll install one there, too.
