Some analog VOMs put out enough current to fry a mixer diode.

Hi Bill,

?

When I first read your post I thought you did some very low frequency stuff.?

Actually you're referring to MHz (Megahertz), not mHz (Millihertz).

?

Since you left the unit running for a while until the fault condition appeared: did you re-check once it was cold again? Like after 24 hours?

?

cheers
