The only reason I can think of for nichrome is that
there would be a uniform resistance in the wire
(likely) or (unlikely) nichrome is a poor (for a
metal) conductor of heat.

My Tek 1230 is definitely plain old IDC, and that
model is worth up to and including nothing without the
probes. Probes are $400+ (without the grabbers!). I
have 3 and have turned down an offer for $300 for one
of them.

I spoke with a surplus test equipment supplier and he
told me that these are almost always lost when they go
up for auction, especially military. Off lease, they
just bill the customer and dump them surplus anyway.

I actually looked into building a probe - no
schematics, no info from TEK, custom and proprietary
IC's, and I suspect absolute analog comparator voodoo
designed for clean and fast risetimes.


Bottom line: you need to get your dough back. Accept
no less.
