Up for your consideration is this vintage 1950 United States military dynamic mutual conductance tube tester, model I-177-B manufactured by Simpson. There are several versions of this tube tester that were contracted and manufactured by several different companies. Some of the more common were Daven and Triplett. Even though they were manufactured by different companies,they still had to adhere to the strict military specifications. The only thing that varied from one manufacturer to another was the components used in assembling them. What is nice about this set is it was manufactured by Simpson (somewhat rarer), it is the same company that built another fine tank, the beloved Simpson 260 multi-meter. I tested this tube tester under normal conditions and allowed it to warm up for 15 minutes. I tested it with known condition tubes and it worked satisfactory.The line cord is a little dried out and should be replaced. It cracks a little when straightening it out. As with any vintage electronic piece of test equipment, I would I HIGHLY recommend getting it tuned up and CALIBRATED. There are no guarantees with this set, it is being sold "as-is".
