AE EP#7 Heathkit V-7A VTVM Voltmeter

This is a little vid about the classic Heathkit V-7A, predecessor of the Heathkit models IM-11 and IM-18. They all had an almost identical Circuit and were manufactured from the 50tier until the early 80ties. I am doing some little repairs on faults that came from a leaky batter and show how to measure with it.
