On the front of it , it says 5000 volts AC and 20000 volts DC.


This is a Heathkit Model MM1

I looked it up on line and am not coming up with much on it because it is so old.

Can anyone else come up with a number/rating of impedance on this thing. I use it to hook to the speaker wires of a CB and set the RX. I normally set it on AC when doing this. I've never tried it on DC. Maybe I should.


Any comments?
