Hi Corby,
in my HP5065A is mounted the old card with discrete components. Can you tell me if there are differences about the final performances of the 5065 using the two different versions? Luciano Luciano P.

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!
