I picked up an old VTVM (RCA WV 97A, actually it does ohms too), and wonder if all the same cautions apply as with other old tube stuff. Dim bulb (I don't have a variac), best to change the old caps, at least the electrolytics, etc? I haven't even had a chance to open it up yet, but anything else I should be careful of before I start tinkering?
