I missed one of these at an estate sale last weekend. $20 with cart and in great condition! I didn't need it, as I have two already, but at $20, I would have snapped it up!

Another Craigslist curve tracer in Wisconsin (I have no affiliation with the seller)
This vintage curve tracer has been in storage for many years. We are trying to find a good home for it. After cleaning it out inside and out, the unit powered up nicely. We haven't run many tests on it other than the basic display and power supply, but it seems perfectly functional. It is listed as fair right now, but that could change if we get more opportunity to test it. We really don't want to ship this heavy beast, so hopefully we can find a buyer in Wisconsin!
If you are unfamiliar with the 575, it is an awesome example of vacuum-tube based equipment. A picture of the vacuum tube deck is provided. It is capable of testing transistors or similar devices with up to 200 Volts and, at lower voltages, up to 20 Amps. See the attached pictures. Let us know if there is a specific test you would like to see verified.
