After I burned in the rig for a couple hours it developed the DOT problem again so then I had to dig further than I really wanted to and eventually found a cold solder connection on the base of Q37 in VCO5. Upon further inspection I also found 3 other cold solder joints on the board so the lesson learned is to look very closely at all of your solder joints for possible cold solder connections that can cause all sorts of problems. Getting parts for these older rigs is becoming more difficult and thankfully I did not have to replace any for this fix.

no longer repairs the DOT problem as he cannot get parts any longer but he does do a lot of other work so check out his page for details.
