The 38-7 does not have a vibrator power supply. It is of conventional design using a power transformer and 5Y4G rectifier.

Part (37) is part of the tone control circuit, and may be replaced with a .033 uF, 600 or 630 volt capacitor.

I haven't checked yet to see where the 10 goes, but I guess I should just follow the schematic, pull it out, and install the 4 and 8 in there proper location?

Yes.
