I bought this from EBay and had to take it apart before heading off to work this morning. I noticed two screws missing after taking it out of the box which is never a good sign, but I did find one of them in the box. In general it is in good shape except for 4 burnt 1K resistors
Looking at Ohmite's website it does not look like they still make the same series of resistor that is in the box. The 1K resistors are marked:
GP 1/2, 1K, 0.1%, TC25
Which I take as 1/2W, 1K 0.1% (duh), and a TC of 25PPM. The closest I saw on Ohmites website was the Arcol MRA series. Arcol is hardish to get in the USA though, not a large selection have I found. I did find some suitable Vishay resistors in the CMF55 series (about $1 ea.). I sent Ohmite a note to see if they have any suggestions from their product line, after all they have to use some product of theirs to make them as they are still a current offering.
