I ended up getting this in a trade sight unseen. It works well but a bit rough around the edges. Two mounting tabs on the bezel are broke. Small wrinkles in the bezel. Wires to adjust bias are soldered to the pins on the board. There are no mods that I can see. All I did was put the limiter back in. I was going to restore it but I have too many radios. $165.00. Plus $18.00 shipping. I can send more pictures if needed.
