In regard to the collet extractor for APC-7, where did you find one cheap? I've been looking high and low for an inexpensive collet extractor without success.

One question I have is how difficult is replacing the N connectors? on a 8753B with an external test set if they are worn out.? Part of what I'm trying to do is is acquire a self sustainable bench.?

I've done it with "flint knives and stone axes'" but that is *very* tedious.
To my knowledge all 50 ohm 3 GHz test sets (85046B) have APC7 connectors, not N connectors. If the test set has N connectors then it is almost certainly an 85046A which is a 75 ohm test set, and best avoided.?
Changing the connectors on the test set is unlikely to be practical without changing the complete bridge, although the collets in APC7 connectors can be easily changed if you get a collet extractor, which you could pick up cheaply. It is most unlikely the APC7 connectors are worn out. Most people put APC7 to N adapters and so the APC7 connectors are rarely used.?
