I recently purchased a partially-completed 4-125A amp from Bob Mayben W4RFM so I now have a box full of surplus QRO parts I've stashed. There's a lot more to come. Here is what appears to be an Air-Dux #195-2. Though there is no number, it has the correct number of windings and size. I don't know if it's silver-plated or not. No corrosion.
Asking $45 plus $15 flat-rate shipping to CONUS. Contact direct:
