Picture post!
Images of Piper the Yorkie and vintage electronics behind
It's picture night! A potential adopter asked for more pictures of Piper. Here's one of them.

Here's another.

This battery came out of the Lafayette VTVM I'm restoring. The only date I could find on the VTVM was 1961. Think this battery is that old? I've never seen one like it and couldn't Google anything about when it might have been made. I'm amazed it hasn't leaked all over the inside of the meter. Sealed in steel indeed!

This is an Admiral-branded 12AU7A twin triode tube that came out of a Lafayette VTVM. Half of the heating filament is bad, so I have a replacement on the way that will hopefully be a big step toward getting the meter up and running.
These are still produced by a company called JJ Electronics in Slovakia, along with a few other types. Their primary market is high end audio for tube-based amplifiers.

A VOMatic 360 volt-ohmmeter (a VOM) made by B&K Manufacturing here in Chicago. B&K is still around and are a producer of high-end test instruments. It thrills me to no end to have something like this that was made right in Chicago most of 60 years ago and is still working just fine with a little TLC. If I do further work on it, it will be testing the range resistors and replacing any out of spec, but it seems pretty on target right now. My test probes for it arrived today and it measures voltage from a battery correctly, and in close agreement with Danae's digital meter.
When I bought this, the glass protecting the mirror was present, but loose inside the case. I cleaned and reattached it, and cleaned the anti-parallax mirror as well. I fixed a tiny bend in the indicator needle, and (hopefully) unstickied the movement with a little canned air at the base. I'm going to clean the Bakelite case too, once I decide on the best way and have a little time.

Closer detail. How about that 6000 volt range?

The VOMatic 360 next to it's modern-day close equivalent, a digital multimeter.

She's going to be meeting some adopters this weekend. I had a nightmare last night about her ending up at the shelter I used to work at and being treated badly. This will be difficult for me.
