@raek (The EICO, before and after. Also, it didn't work before. It does after. ^_^

Before I really get into tearing down the #EICO 145 signal tracer and replacing the #electronics, I may as well take off all the knobs and things for cleaning.
It also means I get to play with my ultrasonic cleaner.

Hey, all back together! And it even works, despite that weird spot which I’ve realised could very much be my cheap little $60 oscilloscope being weird at me.

This time I think we’re actually good. It doesn’t even seem to need any glue between the new brass end and the original acrylic but I’ve put in some epoxy anyway to help it last longer. I’ve got it stepped off the front knob socket _just_ a tad in case there’s any glue seepage but 1) it’ll work perfectly this way too (moving it forward adds no strength) and 2) it won’t seep like that, I’m just being paranoid.

OKAY. Adjusting the assembly by hand works. I just need to fix the physical linkage.
And replace that bulb socket, I’ve found a crack in it and my bodge isn’t going to hold.

I do not normally consider Evapo-rust to be an #electronics repair chemical and yet here we are. Only late-era #EICO would use a light bulb to add impedance to a circuit. Or at least I think that is what they’re doing in this 379 signal generator, anyway.
