Just an observation as an outsider the the USA there is very little Test Gear on Evilbay as a % coming from the East Coast and in particularly the NE  :-//

Is it a lack of Bulk Sellers, lack of industry or a tightass thing that sees Craigslist being used?  :-DD

I haven't paid much attention to the distribution of test equipment on Ebay but my last 3 Ebay purchases were all in the North East where I'm located.

The 465B and 2430 came from a bulk seller in New Jersey.
The 465B parts mule came from a bulk seller in Baltimore, Maryland.

And purchases in the past have been scattered all over. For example. The 465B/DM44 that I bought last year came from the Great Plains of Iowa.

Welcome, Sapper. If you spend too much time here, it's a collection that's bound to grow.
I don't think that will be a problem to zapper, he is already fixing his crosshairs on another scope without our assistance. I think he is just for a new circle of friends who won't question his addiction, zapper we warmly welcome you to the group, you fit the mould perfectly..

Later today I'm going to be making a short (under 2 hr) road trip. If the trip is successful I will be making the best score ever. It will even beat the $65 USD Tek 2465 score from last year in terms of value/goods received. I'm not going to reveal what it is just yet. When the transaction is complete I'll do a full reveal. If the deal goes belly up I'll reveal that too.

Stay tuned.  ;D

The deal was consummated and here it is. Tek 7904. 500MHz of analog goodness. Included in the deal is a 7A26 200MHz vertical, a somewhat uncommon 7A24 400MHz vertical which is genuine 50 ohm input only, and 2- 7B80 timebase. The price for all this goodness? $100 USD! The caveat: it doesn't power up. It has the classic switch mode tick-tick which is usually the caps. Most likely a bastard tant. Should be a straight forward fix.

As you can see it fits on my custom scope cart because I designed originally with a 4 slot 7000 series in mind. So the 3 slot 7603N has been kicked off. I'm also going to have to source some FET probes in order to utilize the 7A24 vertical plug-in.

To say I am tickled pink with this find is an understatement. It's like being reunited with an old friend. The last time I had my paws on a 7904 was sometime around 1977.   

And here's the proof. The Craigslist ad.

Wish I had a Craigslist like you do around here.  Some wanker is selling a used Rigol 1054Z for $500.  Normally, I laugh and move on but I felt required to let him know new ones are $150 cheaper.  I did so kindly but I doubt he will take it that way.  That's why I used a throw away email account.
Yeh, see dickheads like that almost daily, chuck in a few LEDs and knobs and a meter or a screen and instantly they think that it's the jackpot and that they have priced it to go, poor deluded bastards. [emoji23]

We are more likely to find a dodgy car or broken chair on our local version Gumtree. |O  I did find @Brumby an Oscillator a while back not far from him but it's a rarity.

Welcome, Sapper. If you spend too much time here, it's a collection that's bound to grow.

Welcome too 'Abandon hope all ye who enter here'  ;D
Over here we have Gumtree and Shpock and though you can sometimes find test gear on it it generally falls into 2 camps, 1st one is local but overpriced crap that should be in the skip or, 2nd one, reasonable price and condition but its the other end of the country and not worth the trip incase it does turn out to be well presented junk [emoji57]

No it disappears when gnif cocks up instead  :-DD

Everything is ephemeral. Enjoy the moment. Just try not to do it on Facebook as it’s a sack of shit.

Back in 1986, in the middle of the home computer boom, the BBC (I think it was) decided to celebrate the 900th anniversary of Doomesday Book by creating a digital record of everyday life. The main difference is that you can still read Doomesday Book - as I did when it was on show at the British Library Anglo-Saxons exhibition a while back.

Nice!!! I've had decent luck with my P6201 on my 7904A. It even has probe power in the rear, but it's just easier to use the external 1101 supply.

My local Amateur radio club has had an interesting 24 hrs,
Last night we got a presentation from a local Ham, Steve VK5SFA (who also happens to be a braodcast engineer ) who won the 2019 ARRL Antenna design of the year with his double magnetic loop antenna for 1.8MHz - the design and construction is on his website
http://members.iinet.net.au/~sadler@netspace.net.au/tmla.html
At midday we had our Buy and Sell - not a great lot of sellers this year - but I was not unhappy with my purchase from a fellow Club member of some real and working "HP iron" - the past owner is very careful fellow so you know it has been well looked after. Great price AUD$50  :-+

Yeah as the only geek in the school at the time I actually worked on that back in the day. We had to submit articles using viewdata! I did something to do with coastal geography. Booooring lol

I knew someone who had a working laserdisc, master and full set of discs back in the late 1990s that were just tossed in a skip. He sold them for a stack of cash and used it to put a down payment on a lotus Elise he was too fat to get into which we found terribly hilarious. I couldn’t get in it either at the time either so I shouldn’t laugh  :-DD

Edit: lots of schools were issued with Domesday players but during the IT exodus away from Acorn in the 90s they had no idea of the value and they were just tossing in skips. Teachers were totally dumb in this respect. Now there aren’t many working laserdisc players out there. I made a small fortune out of this as well skip diving Acorn kit post disposal and selling on yahoo auctions 1999-2001. No Domesday for me though :(

I think Bean was implying that more gear is available on the West Coast vs the East Coast. He's probably correct and it makes perfect sense. For one Silicon Valley is there. And 2nd HP is in Palo Alto, California and Tek is in Beaverton, Oregon.

That's a good 150 miles or more away from me. Some interesting stuff. Looks like the stash of an SK (silent key) and the family is getting rid of the equipment. Pix 3 on the right.....that 3 inch Heath scope. Would love to have that.

As far as my immediate area (Hudson Valley Craigslist) it's rare to see any sort of test equipment. But it is a good source to snag some occasional decent audio equipment once you sort through the junk audio and the way overpriced vintage tube gear. But if I expand my search to NYC metro area that's where these TEA gems show up.

I was looking at FET probes on Ebay and holy crap.  :o Are these things made of gold? And it appears that half of them are missing their probe tips.  :-// What's going on here? The probe monster eating them? But I'll bet a lot, if not most, are blown out due to excess voltage.  :palm:

I wonder if it's possible to make one with decent response?  :-/O
