EICO model 249 VTVM


 

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.) and observing a fluctuating voltage.

My high quality reprint manual for the above and other models are available.
