One of the best finds of mine was a very nice Type 576 Curve Tracer (at a
great price). The 576 has indeed helped me repair other equipment. More
importantly, it has greatly increased my understanding of all these little
pieces of black plastic with various wires protruding from the sides.
That's exactly the model I would like to find. The 577 is smaller but lacks the ability to do A-B comparison testing. The 576 can do vacuum tubes too, with the right test fixture if I'm not mistaken.
