Some time ago, I restored an S-38, which included building a separate box containing an isolation transformer with plugs and sockets.  But the S-38 would not make a CW tone.  It uses a hokey feedback scheme where a wire is brought near the I.F. amp to give some capacitive-coupled positive feedback. No matter how I adjusted this "magic" cable, it wouldn't oscillate.

I don't really care to fix it.  I will never actually use this receiver for anything.  These things are selling for about $40 for a clean one.  Not worth advertising it and having to box it up and take it to UPS.

I repaired one of these where the customer ( or someone...) thought the wire had broken off and soldered it to the socket.  That was the end of that tube....
It did oscillate with no fuss, once the repairs were made

Never underestimate how stubborn an old curmudgeon can be!
