I have the cathode indicating band corresponding to the cathode “+” indicator on the Selenium in the schematic.
In other words, the cathode side of the Si diode is in the same position of where the “+” side would’ve been on the Selenium. I guess I’m aware of “discrepancy” between how Seleniums used to be notated on schematics. Anyway, if I orientate the Silicon the opposite direction, hardly any signal is displayed on screen, which was the situation prior to replacing the bad Selenium diode.
