RCA T8-18
#37

Sometimes you can't rest until you have figured something out. I noticed a discrepancy between the schematic and the way the radio is actually wired. It is wired as the layout diagram shows, NOT as the schematic, both in the RCA manual and the Rider manual shows! I checked this out tonight. I wired in the components that are missing in the layout diagram and tested the radio. It made no difference at all in the functioning. I suppose this is a modification made after the schematic, but before the layout diagram, but was not noted in Rider's where the layout diagram appears. In the time since I first redid this part of the chassis and tonight, I received 2.2 MEG 3 watt 1% resistors, so I replaced the 2 MEG + 220K I had previously installed when I returned the radio to the way the layout shows.
