People still keep dropping off all this junk!

[Opcom]

Maybe premature but inbound is:
 
"real heavy 4 ft tall cabinet thing on wheels with a big tube and a weird coil thing in the top"
"cabinet that says spectrum analyzer and has an orange screen"
"Tektronix model 505 scope".

At least I know what that the 505 going to be like. Last time someone told me they had a big tube it was a sweep tube. Still a '4 FT tall thing' that is so heavy it needs wheels seems promising. Where does all this stuff come from? Maybe get some pictures later. Wish for the best loot!

The 505 never turned up.. ?? ok, but here is the stuff.
It wasn't described to me very good before. This is from an old ham operator, he's just trying to clean out a bit.
I am really grateful for once that the fellow isn't already dead, when I am called or when someone calls and is coming over with a load. I still don't know why people bring these things to me. No complaints tho, I like to piddle with them. For example, hours of enjoyment getting a 27MHz spectrum analyzer up.. simple but entertaining. Anyway, enjoy the pics!

One thing, the choke in the RF amp is a Thordarson T-47174 or T-4717A. Does anyone know what this is? It's not in my catalogs.
HV XFMR and caps not marked at all. 3B28's for the rectifiers. XFMR looks like it has a HV rated CT, seems potted. Would be nice to know of anyone has seen this kind before. Reminds me of a Langevin.

What I hauled:
4-1000 GG RF amplifier, with tube and all, but taken apart.
Singer 1KC-27MC spectrum analyzer,
HP 410B VTVM /Ohmmeter in rack
10KHz nixie? counter
12V regulated supply from repeater (one of two, I don't know the amps. 10-20?)


what I left for others. In Irving TX.
Lavoie military spectrum analyzer TS-1101/UPM-84 220MC to 40.88LMC
TI terminal (the keys just snap back on)
3-section 6A per section 120V 'variac'.
Other 12V regulated supply.

more pics of amplifier. It might be complete-able.

Some good parts in that amp, assuming you don't want to resto it.

The other stuff. The rack with the meter is in is about 36" high. I need tall racks. This short one might be able to be bolted between two high racks so that its base is level with the work bench, and used for lighter weight gear. why not? The part of the rack behind a workbench is mostly unusable except storage anyway. There must be made a tip-proof scheme for the racks at some point. Just a metal plate on the floor maybe.

HP 410 with the RF probe, including the tube which is hard to find. This is a kind of gear I like. hard to mess it up too.
There is supposedly a "T" like connector for this, into which the probe body, sans tip, locks into, and it measured RF volts off a coax line that way without disturbing the circuit. It's not present.

In the bottom is an audio spectrum analyzer TS-723C/U. Looks like it is more for measuring distortion from 20Hz to 20KHz, and has no automatic sweep. It reminds me of a frequency selective voltmeter. Time to find the manual, hopefully free.

On top is that nixie counter. The rusty thing is the 12V supply, he said it worked. OK sure it did at some point. easy fixing though.

pretty junky stuff this time. parts is parts.

The amp is probably worth putting back together. The transformer looks a good size and is about 60 lbs, so ought be good enough for AM. The rack has side vents, so side-mounting it to get height isn't an option. There is no bottom plate for the chassis or a blower, but there is a centrifugal blower here somewhere that's more than enough for the tube. The spacing on the loading cap is small but no smaller than in the SB-220 and other amps. First the power transformer needs looked at to see if there is enough volts for a 4-1000 in GG. No one knows if this had ever been completed or ever worked. It looks like at least two people worked on it, one doing good work and one doing sloppy work. The OM said he got it that way 20 years ago from someone who had it for 10-15 years. poor old project amp..

Got my van back from the body shop today.

What does this have to do with the junk?? 

On the night after parking the van full of stuff in the drive way, some night-crawling thief with a screwdriver and maybe a crack pipe decided that the big racks of that junk were worth something and broke the door locks on the van to get in. $1000 damages. He was apparently disappointed after looking at what was actually there, because nothing was stolen. Too stupid to see upfront that it was a bunch of old junk and too lazy to try to haul any away as tin.

Can we have the medieval punishments back please?

I've ordered 'slicklocks' to add to the security. That ought increase the work level to above the lazy bum's tolerance. A pro won't bother with a van full of big heavy stuff. Also will add a paging alarm with microwave sensors so I'll know when to get up out of bed and do a little night work myself.
