I’ve finally got the EICO all back together and basically finished. It even works, despite that weird spot which I’ve realised is rather likely my cheap little $60 oscilloscope being weird at me. I’ve put some photos up on my Mastodon account, you can go look. I don’t have really any before-and-after, though – but I do have one, at least. It’s the least improved part, of course, because the front panel was in far better shape than anything else as it turned out.
But here it is:

I was just talking about this project with Anna and I’m like… this was supposed to be just a repair. Maybe extensive, but also maybe not. Replace every electrolytic, probably a couple of other pieces, up and running. It looks crufty but it’s not so bad.
If the transformer inside had been bad, I had planned to bail. But it was fine, except for having to re-glue the paper wrapper. (Which I needed to do, just btw.) “Oh good,” I thought, “this’ll be easy and quick.”
But the more I dug the worse it got. Holy shit. So much worse. So much rust.
By the time I realised I was going to hand-machine multiple new parts – I was not expecting to have to machine any parts – all that was left between “functionally necessary repair” and “complete object restoration” was stripping and sanding down the front frame and re-creating the back panel label.
So I did.
Honestly I’m glad I did it – though now I get to wait for the other parts to start failing now that it’s back in use. xD
