I have this 5H40 chassis that I've recapped and am ready to put it together but someone has put a diode (checks good) in parallel with the selenium rectifier(bad?) with out disconnecting it. It doesn't strike me as proper why not cut out the selenium and do a proper job? Also shouldn't R21 be increased from the current 130 ohms to account for less of a voltage drop across the diode? Also C31 .047 was blown wide open I replaced it with a safety cap.
