An Olson TE-189 C-R Analyzer - Rebuild, part 3 - finishing up with parts and wires.
This unit has been one of the more interesting devices I’ve picked up at a show. It’s not age related problems, it’s poor build quality from the get go. I think I’ve said it before, but I wonder how this thing got in such a bad state - were these even sold as kits? All of the screws were coated with some odd loctite material, so it appears to have come at least partially assembled…
Regardless, after waiting for the correct wire, I got started again. The wire went on quite the adventure, from Illinois to Ohio, where it visited some suburbs of Columbus. It headed out to Kansas City and visited both states that city occupies before heading to Indianapolis, and finally back to Columbus where it didn’t get delivered. I actually ordered some more wire and got that first - even though the vendor shipped me the wrong gauge! It will still work, however, so onward!
The last portion that really needed rewiring was around the input area:
I did find out that the terminals in that big capacitor are just sitting in little solder pots, so I took the opportunity to clean up a blobby one.
Along the way, I did the meter wiring:
and the potentiometers:
And that’s it. We’re left with a cleaner looking chassis:
and all that’s left is to apply the labels.
A little bit of discussion on what was replaced in the next part, and then for the test. Stay tuned!
