[time-nuts] Any experienced HP 2804A thermometer users out there?

[Brooke Clarke]

Hi John:

Thermal Grease?

Speaking of which, our projection TV had a major convergence problem caused by 
the failure of the responsible ICs (the ones with the huge heat sink). 
It(they) may have died because the old style (120) thermal grease degrades with 
time according to Wakefield.  The newer 126 does not have that problem.

waiting for the ICs to get here.

Have Fun,
