Ed,
Appreciate your insights. I actually was able to buy 2 dead units and bring them both back to life. Since both work great after repair, it seems that the prudent thing to do is to keep them both and sell something else? After all, there is nothing else that can take the place of the TEKTRONIX curve tracer. I have found that they are essential in repairing all other forms of old electronic gear. I am interested as to what others say on the subject as I am trying to expand my knowledge of these instruments. Learning what these things can do is a more difficult task than the actual repair of the instruments.
Thanks Again!
