Watching. I had a similar experience. Gear in closet but lots of smoke and
water damage to all most all my 5K and 7K PI's.Luckily the 7K mainframes
were not in the building. Instead my primary 5403 was soaked when the drop
ceiling fell from the water. After a year or so of setting in a warm
house I carefully powered it up and with some control and switch cleaning
has been fine. Lucky I guess. Cannot say how well calibrated it is but my
limited references indicated that it was good enough. So good luck. I
will never get around to going over the many PI's that I have as severe
Arthritis has set in and working small controls is near impossible. Bill

Subject: [TekScopes] Smoke damage 7704A

I have a 7704A that was damaged in a house fire. The scope was in a
closet upstairs and everything outside of the closet was either melted or
burned. There is significant smoke residue on the outside of the covers
and possibly some overspray from fire hoses. I have not yet taken the
covers off; no knobs frame plastics are melted on mainframe or plug-ins
which look externally smoked up. (7a18, 7a26, 7b50, 7b51). I believe
powering it up would be foolhardy as carbon conducts. My inclination is to
completely disassemble the frame and wash with water the electronics and
allow to air dry. Due to age I am worried about old plastic flat cable
connectors and the acquisition to display unit connector. The CRT
connector and the HVPS also worry me.

Does anyone have any suggestions/comments/insights/experience WRT this
situation?

Thanks,
