Vintage Heath VACUUM TUBE VOLTMETER, IM-10 for parts/repair

I plugged this in and it powered up, was in process of zeroing out the ohm meter and heard a little pop, and the magic smoke came out. I was unable to put the smoke back in so am selling as is for parts or repair.

Can use a bit of a cleanup, some wear, not too bad. Also will be selling a large red DC high voltage probe that I got with this separately.

Send your zip code for ship cost- should be between $6.95 and $14.95 if you are in the continental USA (Nov. 2012).
