Nice day at the MIT Flea today. There’s a good sized crowd of buyers.

I had a great time at the MIT Flea today. I bought a season pass, but family events kept coming up (and also the spring Kutztown show), so today was my first flea of the season. August is usually pretty slow, but there were lots of people attending the flea today.

Test equipment was a bit thin on the ground, but here’s what I saw.

Image
One fellow had both RM45 and 545 scopes for free.

Image
I wish I had the room.

Image
He had a nice Leeds and Northrup Millivolt Potentiometer as well.

Image
There was a Meguro 455 KHz IF sweeper with built-in scope.

Image
Sorry about the camera shake. It’s a model MSW-710<something>.

Image
He had a very nice Stoddart field intensity meter setup, with two external external meters, equipment case, and who knows what else. I had to leave before temptation overcame me.

The Krohn-Hite audio oscillator was briefly tempting, but I really prefer the tube models.

Image
Some guy brought a lot of what looks like cell phone microwave test gear.

Image


Image
He did have an HP DSO …

Image
… as well as a lot of lab glassware.

Image


Image


Image


Image
There were a couple of Triplett 630 VOMs, or the Bell version thereof. I saw three or four Simpson 260s, but didn’t bother to take photographs. Most were pretty grubby.

Image
A GW Universal Counter, model GUC-2020.

Image
An HP 141T spectrum analyzer with 8553B and 8552A plug-ins. Said to be working. I ended up taking it home, but haven’t tested it yet.

Image
This Fluke 8120A Digital Multimeter was interesting. Looks like a Nixie readout, it looks like five digits but they’re spaced oddly. Oh, I looked it up at RadioMuseum.org, it's four and a half digits plus a +/- sign display. Maybe I should have grabbed it.

Image
I also picked up a nice example of a Heathkit IM-13 VTVM. I’ll restore it and flip it at some radio meet.

Image
An HP 4192 LF Impedance Analyzer.

Image
An ACDC Electronics Electronic Load. IIRC, we used lots of ACDC power supplies in the IPL 370-compatible mainframes I used to work on.

Image
A Power Designs triple-output power supply.

Image
A batch of Weston AC current meters.

Image
250/500 mA.

Image
10/20/50 Amperes.

Image
An RCA VoltOhmyst Junior

Image
RCA transistor tester

Image
An RCA WV-97A Senior VoltOhmyst.

Image
An RCA WV-77E VoltOhmyst.

Image
A hefty DC power supply of unknown manufacture.

Image
The Archerkit version of the Micronta Range Doubler VOM

Image
A Sprague TO-6AS Capacitor Analyzer. I didn’t ask his price, but if the numbers on the tape on the top were the asking price, it was pretty high for the MIT Flea.

Image
He had a couple of emission tube testers as well.

Image
I believe they were still unsold as of 11:30 AM, when I packed up and left.

Image
There were a few non-test-equipment items of note, like this stack of Drakes ...

Image
… and a KLH Model 41 reel to reel tape deck.

Image
I had no idea KLH made one. I wonder who made the transport? It looks vaguely Sony-ish.

Image
A nice Sony SW-55, but in need of repair.

Image
DuMont and Revere vacuum tube portables, along with a Channel Master and I think a Zenith tabletop.

That ACDC load is nice. We use the same one at work for testing power supplies.

I skipped the August flea (went to a car show instead), but am looking forward to September!

EDIT: typo

I'm going to miss September, but plan to be at the October flea.
