 I foolishly took the faceplate off my R-1051 so I could get it clean & repaint it. After cleaning it I decided repainting was not required. It is never going to be a new radio so I can live with a few blemishes on the faceplate. Also, I checked into silkscreen costs and that was the deciding factor.

I took lot's of notes and pictures & have it all back together as per the schematic. Only one caveat. There is a large power resistor mounted on the aluminum vertical support & shield plate that is is right behind the front panel. R-23 is printed on the vertical support plate and the power resistor is mounted with 2 each  4-40 screws to the plate. The resistor has a value of 64.9 Ohms at 10 watts. One end of the resistor is connected to the 100CPS control board at a point that says +20VDC from A2A6. My question is where does the other end of this resistor connect? I cant find R-23 on any of the schematics. Can anyone help?

I have the updated version of the service manual & I can find R23 on one of the top photos. I just cannot find a R-23 o any of the schematics  with this value.
