The vacuum tube volt meter (VTVM) is a must for any vintage audio, radio or television technician's workbench. I know, the digital DVM's have taken their place and give a more accurate reading and should also be part of a complete workbench. However, there are instances where the VTVM is more reliable than many DVM's. A couple of examples are; measuring continuity of inductors (chokes, transformers etc.) many DVMs will give a false reading. Another is observing fluctuating voltages (observing the meter pointer swing). For those seeking a nice, reliable and calibrated analog instrument, the above has been carefully and meticulous serviced and calibrated.

Measures AC & DC voltage:  0 - 1500 volts.
Measures resistance: .1 ohm - 1000 megohms
