OT : Tektronix 475A Scope...

Sometimes you just get lucky. My 475A lives!!!!!!!!

Although I am somewhat embarassed to admit it, the scope had been sitting in
a storage area for quite a while before I needed it a few weeks ago. I
plugged it in, smoke and smell! Pulled the plug (and cursed fervently).
Since I got the links [see below] from Antonio, I opened up the scope
expecting the worst. The "good" news is that a combination of cathair and
dust appeared to have made a nice little arc near the power-supply. Since I
pulled the plug quickly, and the "fire" did not catch, there is no apparent
damage to the scope, a good cleaning and all is well.

The main reason I post this is as a friendly reminder to check the internals
before powering up a piece of equipment that has been in storage. Although
the scope is fine, my project is two weeks behind schedule [and I am taking
daily late delivery fees!].

David.
