[time-nuts] HP 5370A Frequency counter Problem(s)

[Jack Hudler]

On HP gear, I used a tire cleaner (Eagle something). 
It's the only thing I found that removes that cigarette tar stain 
Note: make sure any stickers and goo from stickers are gone before tire
cleaner.

Then I polish the face with rubbing compound or touch up areas with paint
and coat with a urethane semi-gloss clear.

I can restore a heavily damaged face (Scratched to the metal) to like new
with a few hours work. (Curse those idiots that scrape of stickers!!)

I just pull the board (it's fairly obvious how, but I believe the manual
also talks about how to disassemble the front panel), take the sliders out
of the switches, and swab everything down with Caig ProGold.

The only tricky part is paying attention to how the springs are installed on
the switch sliders.  If you put them back the wrong way, you can bend or
break the spring when you try to operate the switch.
