Hi, all, I have a Heathkit TC-3 tube checker, including manual and prints, available. Image here: http://ana-3.lcs.mit.edu/~jnc/tech/jpg/tmp/TubeChecker.jpg It has been modified with an after-market Coletronics panel with a bunch of additional tube bases. Condition is unknown; it probably hasn't been powered on in some years. It was in my wife's father's basement, so it was in a cool, dry space, at least. I know this isn't the best list for this, but I'm not on those lists; can people here who are, please forward it to those lists? Any interest, reply to me only, please - no need to litter the list!
