I would highly recommend finding some young people like me in your area that are
interested in learning about our kind of electronics, and not only giving them some
of the equipment, but teaching them to use and maintain it as well.

I'm not sure where you got the idea I don't _need_ money.
I'm a native born electrical engineer in the USA, a country
that is hell bent on destroying the profession, so by
definition I don't just _need_ money, I *need* money.

Hi Chuck,

The answer is obvious if your decision is driven by economics: scrap.

Not too many people feel the need to spend a three-digit amount or more, on an obsolete analog scope.

I've listed a fully-operational and calibrated 2467 on eBay for $499 and have not seen any interest. That's the lowest price listed for a working unit of that model - others are trying to get close to $1K or more.

Subject: [TekScopes] Question on what to do with 4 pallets of scopes...

?

Here's the thing:

I have 4 pallets of tektronix scopes taking up space in my
warehouse. One pallet is mostly 7000 series, with a few
5000 series mainframes, another is a mix of 7000 and 5000
series rack mount scopes, with a 564. The third is mostly
453's, 454's, and a few odd 434, 464, 465, 466, 475, and 485's.
And the fourth has a 585A, 545A, and 535A on it... the '45
and '35 were beautiful before the tube whores stripped them...
but recycler's don't get the luxury of judging, they just take
what they get.... ixed in with all of this are several large
boxes of plugins... nothing sexy, but the usual 7B53A's, and
7A16, 7A26, 7D14, kind of stuff...

I love cleaning, fixing, calibrating and restoring scopes
into good working condition. I have all of the Tek specified
gear for doing this, but judging by ebay sales, buyers don't
seem to value that effort at all.

To give you an example. I found a DOA 434 in my stash, and
because it was so cute, I cleaned it up, fixed a power supply
problem that stumped the original owner, replaced a tantalum
on one of the boards, fixed a really nasty trigger problem,
that was caused by the power supply problem, lubed all of the
pots, cleaned and lubed the panel switches, and fan, cleaned
the attenuator contacts, and did a complete calibration. It
took me a week of evenings to do the work. When it was put on
ebay, as cleaned, calibrated, and guaranteed, it got a couple
of $15 offers, and it remains unsold... as does its twin that
I did in hopes of a better result...

At current US scrap prices, I can get $17 per pound for gold
plated circuit boards, which is the standard price recyclers
are giving these days... I work with a recycler, so I am very
sure of these prices... There is easily 2 pounds of circuit
boards in a 434 [vertical, horizontal, storage, preamps, and
power supply are all gold plated]. The 453's and 454's have
easily 5x more...

Considering how much you folks are yipping and yapping about
tunnel diodes, and how hard they are to find, I could have
gotten more than $15 if I simply removed the two diodes in
this 434, and sold them on ebay. And I would still have a
good CRT, the aluminum from the chassis and can, the gold
plated circuit boards, a bunch of special IC's, etc... I have
gotten $5 just from a knob, and $15 from just selling one CRT
filter!.... to sell.

What's the answer? I keep hearing about how much you guys
love Tektronix and their scopes, but when one sells for less
than a tankful of gas, I have to wonder if it is all just
dreamy nostalgia talk. When a couple of days worth of cleaning,
repairing, and calibration is worth less than you would pay
for a dinner out with someone you don't even like all that
much... Where is the love?

What's it to be? Do I fix them, or Do I scrap them?

What shall I do with these scopes?

Hi folks,

? Just a random question in the event there is an affirmative answer: ?Does anyone know if there are any good electronics surplus stores in the Philladelphia, PA area (USA) where one might be able to pick up old Tek Scopes or HP test instruments? ?Just curious, as I might have an opportunity to check it out.

? Has e-bay put all of these places out of business? ?Surely there must be *some* brick-and-mortar warehouses left, no?

I use RTV sillycone. Just a dab in the bottom of the knob then push it on. Let cure for a day and you are all set. Benefit is you can still pull the knob off in the future.

Does this affect all four channels? If so, I would suspect a problem in the vertical output, perhaps as simple as one of the CRT neck leads ha come off, or something in the vertical chain has failed. Channel switch or vertical output hybrid.

My trusty 2465B now has a vertically offset display on the CRT. The bottom of the normal display is now at mid-point. Has anyone seen and solved this problem? Where do I look for the source of this problem?
Thanks, AL

I've used E6000, a soft vinyl-based adhesive, with good success on re-gluing buttons.

I'm not sure which I prefer, clear silicone or E6000. ?You should have some iof both in your kit.
