I remember the old SX-25; it was my receiver for many years. I ended up learning its circuits backwards and forwards.
Another thing I need is an S-meter plug for the S-20R. It's a 5-pin just like on an 807 or other older tube. Can anyone help?
An S-20R parts unit would be very helpful too, with the needed coils and bandswitch wafer and electromagnetic speaker.
