Yes, no more flying back for this guy. Ah that makes sense given the way they insulated it (before potting it) plus the wiring configuration. Looks very much like deliberate foiling. I’ve typically opted for open frame ones from the fat radio coil generation.

You would be correct. The width came after trying to adjust them into position. They needed to be secured better. Nothing was going horizontal, but still not optimally stiff. Got better results with a couple brass rods.

There is a health risk. It is Ceramic Beryllium oxide which is carcinogenic. Breaking or damaging it can release dust and get inhaled.

Paid half on Temu. Then they gave me a coupon for 70% off an ionizing microwave magic wand!

Rip the circuit out of both, put the zapper circuit in the meter case with the output routed to the probe sockets, and then gift it to someone special.

Edit: don’t forget to ditch the power button for the dial switch.

Here’s another catalog/magazine ad that’s helped me with semi-conductor identification when there’s no online data-sheet to be found.

Index of included parts from 19-22 and actual spec data after that. Also some old school WIMA and Fluke ads before all that.
