Lmo unit removed from Heathkit sb 300 receiver that was working but had other issues too great to overcome. Good luck buying. Comes with plastic knob shown, there is a slight crack in that dial.
I was able to tune in cw and Sb signals using this lmo before disassembling the entire receiver. The dial turns smoothly.
