[time-nuts] HP 5065A Nifty A9 repair!

[cdelect at juno.com]

Hi,

Thought I'd share how I repaired a few A9 circuit cards that had a bad op
amp module.

The black cubical op amp module is unobtanium!

I had planned to make a small PC board with a modern opamp on it to
replace the bad module.

Instead I found that I could just plonk in an LH156H and it worked great.

An LH356H would also work, I just had some LH156H lying around.

See the attached PIX!

Cheers,

Corby
