I cannot see where they may have once been in the circuit is the other problem. The caps are #8,9,38 (I think).
If those resistors were back in the circuit would that fix my problem or does their placement not affect the low bias, high b+?.......
It depends on exactly which caps and resistors are missing if they might be causing your problem.
I once had a Zenith chassis that had been hacked on and I had to retrace everything to make sure parts were where they should be. I made a copy of the schematic and used colored pencils to slowly trace things out, correcting problems as I went. It can be slow and tedious, but you need to find what is missing and try to correct it before doing much more troubleshooting.
