Hallicrafters S20R - socket voltages needed

7/22/2011 10:06:58 AMSteve S.

I'm trying to help a friend troubleshoot his S20R by e-mail. Does anyone have a socket voltage chart for this model? Original owners manual and Riders schematics don't appear to list any values.
thanks, Steve

Lower right on the schematic shows where 6 & 340 volts connect. Some other pins are jumpered as shown on the schematic.

If you are looking for tube voltages plates and screens (G2) will be positive, except on 6H6.
