A 140 series, with a round face CRT came out in the early 70's. The 141,

The 141 weighs a ton, but it's rock solid stable, it sells for reasonable
money at hamfests, and it's not that hard to get repaired.

Also, I think the Singer spectrum analyzers of that era are underrated and
sell for very low sums considering how good they are. When I first used
one, I was amazed at how birdie-free it was (although admittedly this was
30 years ago, and all of our standards for birdies are a bit higher).

Unless you get extraordinarily lucky (and when does that ever happen), all
but the 141 series is priced beyond the hobbyist. Maybe some of those 8562's
or 859x's will be still working in 5 years or so when they hit the surplus
market. Till then, hobbyists are still pretty much in the analog SA world.

You know, I like the analogue SA gear. I like analogue scopes too.

I see a lot of wideband hand-held receivers like the Icom R10, some of which
have crude LCD panadaptor displays. Has anyone used any of these as cheap
spectrum analyzers? If so, what is the one that will give me the best
resolution possible? I don't much care about the front end sensitivity.
I can live with some serious limitations in order to have something I can
carry in my pocket.

It would be very nice to have a spectrum analyzer I can carry up to the top
of the tower with me to poke around at the head amps before taking the
whole thing down.

No, there is no person so named. Would you prefer that he had used the sort
of expletives that those symbols generally represent? Have you never seen
profanity annotated that way (think: comic strip)? The 'Sanford & Son'
reference was made by the service rep, apparently referring to the gall of
the OP, for wasting the rep's valuable time asking for information about
equipment that he (the rep) considered to be nothing but junk (you'll recall
the TV series of that name was about a junk dealer).

Does that wrap it up for you...or--OP--did I get that right?

I heard someone on the test-equipment reflector (http://www.qth.net) was
going to fabricate some replacement 8640B gears out of metal. You might
check with that list to see if it ever happened.

Dunno, but the guy at www.odometergears.com has been VERY happy to fabricate
plastic instrument gears for me, for fairly little money.

Thanks to Ed for the good advice.

I've got an HP 140T. As far as I know, the only difference between it
and the 141T is that the CRT in mine is a conventional one with
long-persistence phosphor rather than a storage tube. It uses the same
plug-in units as the 141T. I find it to be very usable, and don't really
miss storage capability at all. I think the tube is a lot more
trouble-free than a storage type unit.

So I recommend that you don't turn down a 140T if you come across one --
and you might even have a better chance of getting a unit with a working
display than with a 141T.

well it is amazing i think how some of these units retain their resale
value even though the companies that made them do not service them or
back them......man who was the brainiac that thought about how to
implement this scam?

incidentally some guy tried to sell a stolen hp unit he lifted over at
his job at nasa.......on ebay.....the final price was i think about
$3,000.00....for a 35,000 dollar unit i thing they said on the
news......he got arrested and the guy who bought it on ebay needless
to say didn't get the deal he was trying to get.....which makes me
wonder how many stolen items are listed on ebay and are sold there?
