So I am digging into the S38B. Nope, not TE, so I won't post more than this here, lest I incur some denizen-of-the-thread wrath...

Here it is, out of the packing box. Manufactured, circa 1953:

I took a lot of photos of the dis-assembly (which raises the odds that the
assembly process has some chance of success) which will get posted when I put up a thread. But here is what the chassis looked like, out of the case:

There was some pitting and corrosion under all that dirt but it was not as bad as I feared. And here's what it looks like with six hours of cleaning later:

That smear at the bottom of the chassis is the shellac used to secure a label. That's also where the isolation transformer will be mounted when I get to that step. The smear will be gone before I finish cleaning the top side tomorrow. Then I flip it over and start working underneath. That will involve mostly removing dirt while I inspect the wiring and parts I hope not to replace. Some guys actually pressure wash stuff like this, others use a dishwasher.

Not my cup of tea.
