On the subject of test equipment, I only just noticed that I lost the
bidding (if you can call it that) on a TEK 555, flea bay. I dont think
the guy knew what he had. It went down to 30 odd seconds then the
snipers came in. Shame really, it had the power supply but looked
tatty, guess it will be gutted and raped for its innards. It would
have been a two hour drive to get it but I was ready to go :-( Item

I don't know if you read my earlier comments on the Tektronix lab scopes,
but I hope this one was not bought for parts. Everything in these
venerable old scopes is readily available. Even the CRT and power
transformer can usually be found. If I remember correctly the 555 was a
dual beam scope with two electron guns in the same tube. These tubes
might be somewhat harder to find. With two vertical plug-ins and two
timebases, it is like having two oscilloscopes in one.
You can still get the CRT for the 585, however, and it has over ten pairs
of deflection plates (driven by a distributed amplifier for extreme
bandwidth). So keep looking.
Also buy a copy of Stan Griffiths' book: "Oscilloscopes: Selecting and
Restoring a Classic"http://www.reprise.com/ash/clients2/book.asp. It is well worth the
money, and Stan is a great guy who is happy to answer questions and help
you find parts.
I rode back from Charlotte, NC, to Kingsport, TN, with a friend who was
driving an ancient Toyota with my Tek 585 filling every available cubic
inch in the trunk. We had to drive over the mountains that night and I
worried about every icy mountain curve. It took two of us to carry the
monster into my house. But it is still my favorite scope, even after 24
years.
Good luck on finding a real "keeper."

The idea of dual beams is what atracts me, plus the amount of plug ins
available. I recently moved house and now have a nice workshop with a
well lit "clean area" for electronics and other cleanish stuff and
another room just off it for "dirty stuff" all mechanical things,
milling, drilling, turning, welding and general fabrication. It does
get fairly cold at night so a big old Tek would warm the place
nicely:-).
That 555 did look a bit lugged about but I am sure I would have had
no trouble repairing it. I have quite a few 6080s and have read these
work quite hard in the PS so at least that would not be problem. I am
a member of the Tek scopes group so advice on any weird thing like
tunnel diodes would be no probs. I will continue my search and will
probably end up with more than I need, I have a bit of penchant for
test gear, much to the dismay of my better half. At least I can hide
away now without worrying about condensation in the old shed or using
the dining room table:-0.
As for picking one up, I drive on average 1000 to 1200 miles a week
as part of my job. We are supposed to be a carbon neutral company, but
I guess thats what happens if you do a good job, they send me to all
the difficult jobs that no one else could be bothered with. Yesterday
a pigeon flew out and hit my windscreen, it scared the sh%^ out of me.
Not much left of the pigeon but the windscreen survived although my
wing mirror came off and went under the back wheel. Must be something
to do with Welsh pigeons.
