An EICO 950A R-C Bridge Part 7: Let’s check the removed components.
Monday, June 29, 2026 at 06:28:49
One of the things I like to do with units I rework is save all of the components and check them when work is finished. Since the EICO 950A has been completed, it’s time to check those parts.
I know I’ve said this before, but I can’t say it enough: This thing was a mess. Someone cut every wire, every part, and J-hooked it back in. The wire…sure, that was some old thread-wrapped stuff and the few pieces left could have generously been said to have insulation. The parts, however? Wow.
Here’s everything that was removed from the unit. Most of what the previous owner put back in was of decent enough quality, even if they weren’t the proper tolerances.
Here’s some of the lovely connections made in this device:
That’s not even the worst of the lot. There were a couple of 4-splicers in there.
For the most part, the components that were newer are still in good condition, with only the resistors being problematic - as carbon comp resistors are. Surprisingly, most were reasonable for their age, so while this thing definitely shows signs of being stored damp, that didn’t seem to affect the components much. I didn’t do a “good/bad” on this one, as most of the parts weren’t original.
In all, this was more of a problem than it looked - slow and steady won here, and everything is back where it should be. Next up is the final check, and then the wrapup post with some thoughts on this unit if you have one of your own. Stay tuned:
