This is an all-in-one-box test and measurement setup for servicing
two-way radios, up to 1 GHz. I have come into possession of one at no
cost, but it also doesn't work. It powers up, the 'scope makes random
green lines, the meter moves, but it neither receives signals (but I can
hear hiss) nor radiates them, as far as I can see (I've used equivalent
units from other manufacturers).

So the questions a

1) Does this antique have a "known failure mode" that I should be
looking for?

2) Assuming I get it fixed, what's the going market for it -- likelihood
of selling it, and what it might go for?

thanks, Isaac

Not that I know of.

I will give you seven dollars if you pay for the shipping. If you get it
here within 7 days, I will throw in a coffee cup with a picture of my cat
on it, but only if you say you saw here it in this newsgroup.

The only Wavetek kit I've repaired , problem was due to a failed tantalum

Is it an 3000B or 3000S ?? Big difference. The S has a spectrum
analyzer.

I have a 3000B that I bought on eBay for very little. I think it was
$300 including shipping. However, it is missing some key components.
If you're interested in selling yours for parts, please let me know
and set a price.

Argh. Sounds major, like a power supply. There are test points on
the power supply board if you remove the cover.

Incidentally, you can get a manual from:

There are some cheaper cd's on eBay.

The most common failure I've found on 3 units is
unfortunately crappy solder connections on the main board
and front panel. Of course, these are the most difficult to
access and repair. Also broken IC connectors on the ends of
ribbon cables. However, the most common problems are due
to the failure of the TI TL-607 FET switch. The chip is almost
completely unobtainable. Fortunately, most of the chips are
in sockets, so are easily replaced. That's one of the parts
I need to fix mine.

There is also the common problem of aging electrolytics on such old
units. It's likely that some of the electrolytic cazapitors in the
power supply are the culprit. Check with an ESR cazapitor tester.

2) Assuming I get it fixed, what's the going market for it -- likelihood

There was someone selling 8 of them on eBay several months ago.
He ended up dragging them to the Dayton Ham convention in
May. I think the 3000B's went for $500 while the 3000S went
for $900 or more. If you want, I'll dig out the old email
and you can ask him for the exact selling price.

Here are some recent sales from eBay:
http://cgi.ebay.com/ws/eBayISAPI.dll...m=180001576997
http://cgi.ebay.com/ws/eBayISAPI.dll...m=190002642826
I've seen them sold for about $350 to $500 (including shipping).
A friend bought a 3000S on eBay for about $1200 2 years ago.

Let me know if you want to sell yours for parts.
