In my Novice days many years ago I owned an SR-75. It was indeed an S-38 that used the audio output tube (35L6 or 50L6 (?) as a TX oscillator with a plug-in coil that was reached through an opening in the back cover. Had no way to measure the output power, but it wasn't much.
The original S-38 (only) has three slide switches in the lower left corner of the front panel. The third switch is for a diode noise blanker, and only appears on original S-38's. FWIW … 73!
