[time-nuts] Replacement A9 boards for the HP 5065A

[Bob kb8tq]

Hi

Teflon is the traditional “best of the best” for integrator caps. Simply finding 
any plastic cap  (other than a motor start device) up around 5 uf is not that easy 
these days.  As mentioned by PHK, being sure it is what it’s supposed to be ….
good luck.
