Re: Wanted: 7CT1N Curve Tracer Plug-In

That's what I thought about using mine in a 7904, so I tried finding
a 5ct1n to shove into a 5103 I picked up for $20. Those things are
even worse.

I finally lucked into a guy selling a complete 5448 setup with a box of
plugins (including a 5ct1n), extenders and cart for $100. I bought it
for the plugin and ended up with another scope.

If I ever find a 576 or 577 for a reasonable price, I'll trade off the
ctn1 plugins.

I picked up a 7CT1N which needed some basic care for about $150 in the
middle of last year. Luckily it was safely packaged inside of a 7904
along with some other plug-ins which protected it from UPS. I managed
to repair the UPS damage to the 7904 as well and now I only use my
7603 more. The 7904 still needs to have its power supply rebuilt.

I lucked out because the auction was not clearly listed so there were
few bidders.

The 7CT1N was surprisingly useful when I repaired my DC505. I knew a
couple of 2N3565 transistors were bad but it identified several others
which were close to failing. That would have been missed by a
standard forward voltage drop and hfe test.

I am a little tempted to design an automated source and measure unit
for transistors that goes beyond the basic tests.
