Even though its been months ago, just unpacked it recently.  |O

Had to brag this, a free DS1104Z that I won few months back from one of the generous member here.  :-+

This was unexpected. I think it's the first time I've ever found any professional high-end test gear as a street toss.
Recently I've been driving around more than usual due to visiting my mum in hospital frequently. This thing was sitting on a kerb on my usual route there yesterday, with some other assorted junk.

It's a Tektronix TG700 TV Signal Generator Platform.
Info: http://www.tek.com/datasheet/sync-pulse-generator/tg700
Loaded modules:
  AG7   6x50 BNC   Digital Audio gen
  DVG7  2x75 BNC   Digital video generator
  BG7   4x75 BNC   Analog black gen (opt CB for color bars - does not have, dammit.)
  AGL7  6x75 BNC   Analog genlock

All my exposure to professional video was in the '80s, so analog video only. This thing is mostly digital video, so quite interesting. It seems to be completely working (its self-check claims) though as yet I don't have any other digital video gear.
When I first started playing with it (before I had the manuals and list of module functions) I thought one module was broken since the menu said it was generating color bars, but all my bench scope could see was HF white noise. Ha ha, it's a digital video stream.
It was dirty and stickered, but cleaned up nicely. Even had the protective film still on the display.
Oh, and miraculous wonder: the rack slide rails are complete. How often does *that* ever happen?

Last 2 pics: At the other far end of the tech-spectrum, in the same pile was a tub of tools that had been left in the rain. Cleaning these up is kind of an obligation to the fight against entropy. Just light surface rust.

I spoke with the people at the house; they are 'clearing out the house for a friend'. Huge piles of stuff already moved out in the yard. Arranged to go back and meet again tonight, to see if there's anything more like the Tek.

Some of those tools might still be salvageable. Pliers(good chance) , hexes/files/clamps(yes) screw drivers might still be good, unless the phillips head is mushed.

Thanks. I'm considering it unlikely - probably that was just something the resident had acquired and didn't know what it was. Mostly I'm just curious to find out the history of how it came to be there. At the time I was speaking to an old Asian lady with no English, via a young girl with not-so-great Vietnamese Cantonese. The guy who knew stuff wasn't there.
But you never know.

No really, when I said "light surface rust" I meant it. All clean now, see pic. Only the two feeler gauge sets were far gone, and even they will do as car-kit.

Those cleaned up really well. How did you do it?

Large diameter steel wire wheel in a bench grinder for most of it. Some concave bits with stainless steel wool hand scrubbing. The files and delicate things like the teeth of the taps, with fine brass wire brush and running water. Then a light coat of oil on everything.

Mainly I wanted the chisels, of which I don't have many already. Everything else was just 'well since I'm doing this, why not?'

A nice haul, especially considering the price.   :-+

And you can never have too many clamps, so one more is always a good thing.

 :-+Those look nice chisels, they are hard to find . Some 6 years ago my father died and I inherited his tools, I used a cone wire brush on an angle grinder then Lanolin (Inox Lanox) or recently gun oil.
Whoah! Watch where that landed we might need it later.

Can you guys get anything like this "down under"?

http://www.evapo-rust.com/

I tried some out a few years ago and was impressed by its performance; unfortunately I don't have photos.

Pat re evapo-rust I've not seen that stuff before, a quick look on eBay Our local car+ Supercheap auto has some, I have a mate who has shockingly rusted tools, I might buy him some as a Christmas present. Not cheap 5 litres AUD $85 .

Bought a HP 8903A Audio Analyzer, posted working but arrived with no working display despite being reasonably well packed, "grace03us" sent a good sized part refund on my word alone!
Opened the lid and after a bit of digging around fixing the 1980s HP "clacky button problem" found a loose cable- plugged it back in and she lives.  :-+
The seller seemed such a decent fellow I resent most of the refund!

Found this beast listed on Ebay AU and it actually got a bid, it's not mine and nor will it be but check out the question mark in the display, a meter with an "I dunno" feature could be handy for some I suppose.  :-BROKE

That's a vintage tube tester! I am looking for simmilar devices for years but wasn't lucky at all, since they always end at a (at least for me) unaffordable price... The questionmark in the meter was to show the transit area in which a tube would work as expected but eventually with reduced power, since theose things most of the time measure just the current going through the tube at the standard datasheet values. You could say that a "?" tube is most of the time perfectly useable, as long as you don't try to squeeze every last µA out of the cathode.

That particular one looks a bit sad and is currently at $20 AUD, they pop up occasionally and there was a really nice tube tester listed only a few weeks back that got 1 bid at $30, I was tempted but passed on it as I'm currently putting a valve radio back together otherwise I would have no other use for these and most are fairly big units.

Valve testers are handy if you have a lot of valves/tubes to test or have unskilled labour that needs to qualify them as good/bad but it's not particularly difficult to test valves without a custom tester, just needs some fairly basic lab gear and some common sense regarding electrical safety.

Tube testers are reasonably good at determining if a tube is dead or shorted.  Whether the tube is actually good or usable is another story.  They were also not laboratory instruments and their primary role was to help service techs sell tubes.  The best way to determine the actual characteristics of a tube is to use a curve tracer.  Tektronix actually made one, the 570, but the audiofools have priced these into the stratosphere (one sold for $2K on ebay back in Sept).

There's at least one modern computer controlled tube curve tracer available and it's fairly easy to use a Tek 576 with some additional setup.

Re tubes and testing, when I was restoring my Tek 545 (all 107 tubes I recall!) i got a uTracer3+ from DOS 4 ever, it is a proper tube tracer but has some nice features in that it doesn't test the tube for long at each voltage so you don't have to get too excited re power limits etc. As the HV is only around for a short time (I recall some milliseconds) your chances of 'exciting' yourself also goes down. The biggest issue is you have to build it and get the tube sockets you want. It is basically a computer controlled 3 power supply (2HV,  one for filaments) and 2 voltmeter 2 ammeter unit with a nice PC interface to drive it all.
PS No interest other than a happy customer.
Whoah! Watch where that landed we might need it later.

I'd feel similar, it's always nice to find a seller who is so fair and makes no fuss about resolving problems.

I guess you can always send a bit back if you feel like it?
