Re: Tektronix 535 scope for coiling use



Original poster: Ed Phillips <evp@xxxxxxxxxxx>

Hi Everyone,

I picked up that old scope I asked the list about, when at his place
before
leaving, it had a good trace on both channels (it is a dual trace scope)
when I got home, it did not work, I traced the problem to a bad Pot,
which
I may have located a replacement in iowa...

I needed a scope, but I am starting to think I need to get a scope to
use
to help fix this one next time it breaks, and I should get a "parts
scope"
or two of this model (535A), so I will have parts.

So if anyone has some old tek scope parts, or a dead 535A that they do
not
want anymore, let me know what you would want for them...

	Which pot is bad and why did it keep the scope from working?  I can't
imagine anything in that scope which would not be easy to replace,
although some of the dual pots in the preamp might be a nuisance.  For
that matter, what's wrong with the pot?  If it's just intermittent or
noisy a squirt of contact lubricant plus a lot of turning back and forth
will probably restore it.  I recently had to go through that procedure
with a CA preamp.
