What led me up to the bias resistor was I just rebuilt C44, the electrolytic with the isolated ground which connects to, you guessed it, the bias resistor R43, as well as the center tap of the HV winding. I am slowly getting the power side of the chassis rebuilt, all the caps and resistors replaced, no micas so far. I removed the bias resistor to get at the 6F6 to replace the various parts attached to it. It is still connected until I figure out exactly what I want to do to replace it. Right now I figure a 200 ohm 2 watt, a 10 ohm 1/2 watt, and a 33 ohm 1/2 watt should be close enough for government work. As I asked before, what have others used in their 37-60 or 37-61 projects ? Alternatively, does anyone know the tolerance on the candohm bias resistors? Not the round one shown in the diagram, but the flat kind in the later chassis, after the bakelite block change outlined in the notes. My guess is 20%, but, it being the fix on the bias of several stages, I would like to know more precisely. If it is 20% I will be fine.
