HP once made a kit with DIP logic clip, logic probe, logic pulser, and current tracer. Pulser and tracer made finding shorts pretty easy. For the SR-620 you could disconnect the regulator and inject current pulses there, follow them around with current tracer. The same basic trick works given a bench type pulse generator as the injector, following the current with a chopped down magnetic tape head feeding a scope (or spec analyzer?). Been there, done that. Made my own RF type probe with just a small coil at the tip. Have the HP logic kit as well.
