It uses 153-0038-00 tunneldiode which is a selected 152-0154-00 which
is also the reason Craig didn't have it his list.
That's interesting - thanks! I'll put that one on the list. The
152-0154-00 is used in a number of things, including the TU-5. The diode is
10mA/9pF, giving a switching speed of about 450ps, which is consistent with
the specification. Assuming wiring stray capacitance of 3pF, a composite
switching speed of 600ps comes out of the calculation.
Others interested in a roll-your-own might be interested that this diode is
also in the RM546, RM547, R544, R556, 1S1, 1S2, 21A, 22A, 544, 546, 547,
556, 7B70 and 7B71.

Didn't realize this stuff was so valuable.
I have a few items I could probably be bribed out of.
Self contained 30ps pulser works
transmission line from same, need to check the diode.
also have a 284 line somewhere in the attic.
its diode is definitely bad.
