Price of Tek 465/DM44


Oz-in-DFW
 

I'm trying to set a price for sale on behalf of an estate. I know what I'd ask were it mine, but I'm looking for some more objective data.

It's:
- in fair shape with a cover
- rear feet have disintegrated
- power cord is functional but needs replaced (cracked in places, aftermarket plug)
- has three scope probes 2 X 6062B w/ one ground lead and one clip an a P6006 with a modified ~2 ft ground lead)
- has a DMM probe set
- passes very cursory checks (lights up, both channels show expected changes on finger contact with probe, timebase change effects display, etc,)

Given the working condition, presence of the cover and probes, and discounting for the damaged feet and cord, based on recent selling (not asking) prices for similar items on eBay, I'd say the value is around $250 (US) (Google tells me that's about $337 AUD).

I think that's a bit high. If it was a 465B, maybe.

Plain 465s are selling in the 50-100 range now, so probably
in the 100-150 range. Maybe.

I got my 465/DM40 with a scopemobile for $75. No probes, but it
did have a cover; that was a few years ago. Can't see how analog
scopes have appreciated much since then.

Decreased supply with age? Increased demand from exposure on YouTube?

I'm not really trying to defend my valuation, but I thought that the whole reason that we Don't Mention the Name of the Auction Site[TM] is that we don't want to start a run on one instrument or another.

Mostly because of the price of capable DSOs. You can get an
entry level DSO for $250-300, with a warranty, that does everything
a 465/DM combo does along with much more. And not worry about
having to fix it.

I love the 4xx series, I have them coming out of my ears,
but part of the reason I like them is they're cheap.

Anyway, depends on the audience he's selling to. This
crowd? Probably on the low end. Youtubers? Maybe on
the high end. Craigslist? Throw in a couple audiofool
words, say $300 and see if anyone bites :-)

A DSO samples the input signal.
If something you are looking for happens at a sample time all is good.
If what you are looking for happens between samples as far as the display is concerned it did nor occur.
This does not happen on an analog scope.
My go to scope is a 453 Mod 703H.
I can display a signal well above the rated bandwidth.

I have no questions, on an analog scope, as to if what is on the display is what really happened.

Well... if you get a chance... if you want to back that up a bit more....I'd like to hear... because the math say's your're claim isn't true... sort of.
For example... I can easily make an absolute liar out of any 465.
And that's not to say, I'm not obsessed with Tek analog scopes: I definitely am.
But the argument that analog scopes are superior to digital scopes is a flawed argument that IMO may be misconstrued.

Hi Jeff:
I'd agree with Paul... that that's "a little high"... and further qualify it as that's too high.
For these 465x... and similar... you know... claim to be "working", "vintage", "powers on" ... and other such flummox... 1USD/MHz might even be too much.
Hey... if you've got money... knock your self out!
But, I thinking in the context of someone who wants to get an oscilloscope to use... not to hold down the basement floor, under the wine rack.
I think it's unfair (even immoral) to sell one of these to an unsophisticated buyer who for a relatively few USD more could otherwise purchase a new DSO. (But "DSO" is another discussion in this thread.)
