I have a full schematic, which may even be mostly accurate, for my VTVM. That's a satisfying accomplishment after all the hours I've put in. It varies from the typical model that I can find schematics for and I don't know electronics well enough to figure out why exactly. Maybe next weekend when I get together with Posi we can figure it out. I'll see if I can get a decent scan of it for people here to see too.

I replaced a couple of wires; one was broken and one had melted insulation from when I was soldering the transformer secondaries. Oops. In know that one of the adjustment pots is bad after doing resistance measures, but I was going to put the tubes back in, plug it in, and turn it on and see if it was generally functioning well after fixing that broken ground line.

Then I realized I haven't replaced the fuse yet, so that will have to wait! I desoldered the fuse and figured out it's 1/8 amp 250 volt, so I'm ordering a pack of those tonight.

Until those show up, I'll probably get back to building that ESR meter that Posi was helping me with. I also bought a nice electronic desktop postage scale that measures up to 60 pounds today! Two bucks, but it doesn't turn on. I bet I can fix that!

I fixed the scale! Just had to solder the power wires back onto their pads on the board. I'm so pleased with myself!
