Probes for DuMont Oscillograph Model 292

I'll be installing replacement caps for the CRT deflector plates this weekend and firing it up for testing. The probe connections on this unit are standard banana type, like for typical multi-meters. Will my multi-meter probes be good enough, or is there a special type of probe that is needed? Any suggestions on what to measure (ie household current) for a quick test? Unit does power up, but had problems centering the trace...

Regular bananna plug/jacks should be ok as long as you are not measuring voltages high enough to break donw the connectors, and that doesn't seem likely.

Don't know what Vin(max) would be for this scope, but I wouldn't recommend 117V. Try a convenient wall wart, or spare doorbell transformer. Using coax rather than multimeter probes would be more accurate for higher frequencies.

With banana jacks standard, I doubt this thing has a bandwidth more than

100 kHz, maybe less.

Once you get tire of looking at 60 Hz AC, try the output of an audio system (walkman, CD player, etc.). I wouldn't risk an Ipod until you know it isn't going to zap it though! :)
