Maybe not.
I had an analog multimeter hooked up to a couple leads checking for voltage for the phonograph... and the radio started to smell burning and the multimeter showed nothing. I quickly unplugged the radio. I have removed the chassis but I don't see any burned or blown wires or capacitors.
The multimeter still works (tested on a 1.5V battery) so it didn't get fried, nor should it have damaged anything in the radio.
One of the vac tubes looked foggy/smokey inside but cleared up after several minutes once it was unplugged
Is that just the sign of a failing vac tube or should I pull each tube and check the sockets?
EDIT: With the chassis removed and sitting on a plastic box on it's side (not leaning on any tubes) and the radio plugged in to an outlet on a switch across the room, one of the front vac tubes is flickering blue inside like lightning some. Is it burning out or what? I didn't smell anything burning, but the multimeter is also not hooked up anymore.
EDIT 2: Now that tube isn't doing that.. but I hear what sounds like sizzling from either a tube or from a power block. I can't tell which and frankly I don't want to get too close to it. Do vac tubes ever explode?
I'd hate to be close to one if they do.
