Thanks, that helps. I could, for starters, check each component that is listed on the Possible Cause side.
I frankly did not realize that zooming that part of the service guide would give such sharp detail of the layout. I would have used that during the recap!

Another thought, since this is not being done for alignment purposes, could I use the cheap sine-wave/square wave generator from my old CEI trainer/breadboard? (Anyone remember Cleveland Institute of Electronics?) It looks like I need a 9.1mc modulated output. Could I try this just to see if/where signal is passed?
