atkelar | Tektronix 576 Curve Tracer - Part 1 @atkelar | Uploaded March 2024 | Updated October 2024, 12 hours ago.
I always wanted a decent curve tracer to check up on replacement parts with a bit more scrutiny. But the price was alwas a limiting factor. And the Tektronix model here is also quite heavy, so shipping usually almost doubles that. By the end of 2023, an online friend said he had to sell off his, due to lack of time, space and money. Add that to another online contact making a journey by car earlier in 2024, and I just couldn't pass up the chance! So, here we are: part one of either two or three (most likely three) of the in-depth restoration of this classic device!
(note: not visible in the video becuase I stupidly didn't think much of it at the time: I found a loose resistor resting smack against one of the test fixture onnectors in it. So any less-deep restoration might have missed that and ended up with a short eventually. So yay! I found a good reason after the fact at least!)
