I need a replacement, used or new, for a small rotary switch on my
SP-600-JX-6. The part is called "S-3" on the schematic and in the
manual. It is the switch, mounted near the top of the gear train plate
on the right, that connects the fixed-frequency oscillator and crystal
bank to the VFO circuit when crystal control is selected as the
operating mode. Actually the mechanics are okay on my switch, and a
replacement wafer alone would do the trick.

With hope, Jim, KF7A
