What's scope cal equipment worth and how to ship it?

I have the three TEK leveled sinewave oscillators
in good working order. The -650 has been modded for
6MHz reference output so I could calibrate a
TEK TDS540 with it...but that's easily removable.

191
067-0532-01 500MHz
067-0650-00 950MHz.

They really need a new home.
Been trying to sell 'em for $100 each at Oregon
swapmeets without success. What's a rational price
for these?

If I gotta ship 'em, how should I do it?
I have visions of them arriving with the tubes
shattered all over the insides. Should I pull
the tubes and ship separately? Other tricks?
Thanks, mike

Well, the last 2 191's sold on ebay for $51 and $76, so you're priced a litle high (but you never can tell about next week or month, ebay is fickle!). It frequently depends on how close the potential buyers are to the seller. I'll bid more if I can pick up for free!

As far as packaging goes, the best filler is the foam that's used to ship electronics (usually pink) it's stiff, but absorbs shock better than styrofoam, and doesn't compress like foam peanuts, paper, etc. I've never had tubes break, so unless the packaging is really bad, you shouldn't have to worry. For heavy items like 7K scopes, I usually double box (the outer box/padding can then be sacrificial), unless I score some really good foam that fits both the box and the scope.

I sold a pristine Tek 191 on eBay a couple of years ago for about $40 or $50 + shipping IIRC. From memory, that was about what I expected from looking at past sales of the same.

Aren't you the guy with the website that has all the
neat stuff for trade like calculators, motorized
variacs, Tek Application notes, and other stuff?

If so, you've sure got a market here in this group!
I've sent you a personal email and look forward to
your reply.

As far as packing, well lets say I'd need to know how
many tubes, location, ....

I'd say not off the top of my head as I've packed raw
tubes and received equipment with tubes sometimes
removed and other times not. In each case everything
faired well.

Me, Well I'd make sure that none of the sockets were
loose. I'd also be wary of removing the tubes
designations and markers by taking them from their
sockets. Sometimes, cause of age, it just rubs right
off. Then for a person like me, well a scratching
head frenzy would begin : )

One way to ease the shipping would be to kinda wad/pad
the interior between tubes with something like a brown
paper sacks material or this other stuff I only get
when I'm mailed stuff. It's sorta like a earthen
color webbing made obviously of some type of woven
paper or fabric. You could easily just weave it
around and over the tubes, leaving them in place.

I'd then make sure to place the entire item in a box
for regularity and foam around or big bubble wrap
around it inside another box. You could even add some
foam or bubble wrapping inside the inner box.

Just a suggestion, for I re-use packing materials. I
rarely buy anything. Sometimes you can get Great
stuff from the furniture stores! That foam in the
sheets that covers dining tables and the finer
furniture is great too!

I ask to dumpster dive on weekends, at least I used to
when I had time. You can even get the wooden sheets
that are like an 1/8" thick too. Sky's the limit.

Take care. I don't think I've heard any of your posts
before but dunno; however, I know you are very
knowledgeable, if that's your website; and you'd
definitely be a great asset : )

Laters.

Hi, mike
probably stating the obvious,but if you do remove
the tubes LABEL them with their chassis/socket
designators so they can be put back in the sockets
they were pulled from. Otherwise the calibration
could suffer
