[time-nuts] "The Penultimate HP5065 A15"

[cdelect at juno.com]

Luciano,

I agree entirely!

I like the motto "do no harm"!

When I try a mod such as replacing the dead op amp on the A9 board. I
make before and after tests to make sure no degradation has occurred.
Since this means parts in 10 -14th AD at 128 Seconds most don't have the
capability. However a lot of Time-nuts can test in mid parts in 10-13th
from 1 to 100 Seconds so can at least compare that part of the
performance.

Mods like HP made to move the bridge rectifier from A15 to the chassis
can be made without such testing.

That said a replacement A15 card to replace a  'Crispy crittered" or
badly damaged one would be welcome.

Cheers,

Corby
