Magnus;
   Thanks.  The one thing, I think I know, is that the defection coils seem to work as expect. That was from testing with a low voltage variable supply.

I have the TAPR TICC talking  to TimeLab,  as a free running ASCII source, but the TICC documentation is a bit cryptic.  I will address the "Nuts" with some specific questions soon.  First need to upload the new software.

Hi Lester,

The 5372A excels in a field where we usually do not go, "high" speed
signals. It can time-tag events every 75 ns (in fast mode, 100 ns in
normal mode) if needed, and it can also do hardware accelerated
histograms. Valuable skills for some tasks. Some have the FFT option.

For normal time-nuts work, you can often use a TAPR TICC and TimeLab to
do most of "our" exercises much more convenient than using the 5372A. To
some degree tha 5372A is old and arcane, but it still find it's uses and
you still can use it as a 200 ps resolution counter, which beat a bunch
of other options. The TAPR TICC has however higher resolution and is
therefore very useful.

The CRT module should not be too challenging to an old tube-ham like
yourself. I had to replace a capacitor. Some diodes looked like they had
been running hot, but they where still operational. I also had
deflection problems, but once the retrace oscillator started operating
things fell into place.
