Default Re: Test equipment for valve radio repair

Valve voltmeters have a much higher input impedance than most normal DMMs. Mine gets a fair bit of use in high impedance circuits. I can't remember the exact number I came up with when I tested mine but the impedance was certainly more than the >200Megs that I needed and that on the 1V range.
