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!)
