Thanks for the info......................I've already got an 8558B, so I am
set. I just removed the knobs for some extras for my own unit. I don't have
much tied up in this unit, and I have already scrapped it.

I know that this is off-topic, but since there are many
homebrewer/designers on this group, I will mention it. I am parting out an
HP 8557A. This is the one with the LED display.
I purchased it from a local hamfest and discovered that the sweep board
had a problem. All of the other boards, including the front panel
assembly with the attenuator should be ok.
Let me know if you are looking for any of the board/assemblies and we can
work out a reasonable price.

This post appeared a few months ago, may be worth an e-mail (or if he
parted out his - and you can get his sweep board!)
