A elderly friend gifted me his restored heathkit lm-13 vtvm it needs a probe but my obvious question is can i use it like a regular volt/ohm meter or no?
VTVM how the heck do i use it?

You might want to check the battery, it's for the ohms measurement only. The probe for dc volts probably uses a 1 meg series resistor in it. To answer your question Yes. And it would be a Vacuum Tube Volt Ohm Meter vtvom. When my pals were reading comic books I was down in the basement in my dad's workshop. Perusing his Sam's Photofoacts Vol 1-50 admiring the old set and trying to figure out what all those squiggly meant. Circa 1966 Now I think I've got! Terry

What the heck is VTVW? Or does W stand for M upside down?
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
