Model 90 B.C. Resistor
#4

Thanks for the suggestions. I decided to remove the BC resistor(s) entirely from the circuit. I brought out my 40x jewellers loupe and was able to find the two broken (TINY!) wires that related to tab 2. I cut out a new tab from some thin copper and was able to carefully re-solder the wires to the new tab. My luck is holding since I checked all the resistance values and they were in the ballpark. So I'm re-installing it into the chassis and re-hooking up all the connections. My new DSO should arrive tomorrow, so I'm looking forward to firing it back up and looking at signals.
