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!)

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.

Hopefully you kept the attenuator

I did, but all of the unit is up for grabs. It is a nice 60dB attenuator.
I've got all of the board in a box..........probably, I will end up taking
it to a hamfest if I don't sell the parts sooner. The LED readout board
seems to be the same as on my 8558, so maybe I will hang on to that.
