Also got a pair of Tektronix generators - a type 106 square wave generator and a type 191 constant amplitude sig gen. I was surprised to discover that both are hybrids with both tubes and transistors, and are from the mid 60s. I'd have guessed they were mid 70s at the earliest. Surprise, surprise...
Tektronix seemed to use GR-874 connectors for almost all 50 ohm stuff in the 1960s. (and maybe the 70s, at least for stuff that was an old design.) I have a nifty Tek amplitude calibrator, 067-0508-00. One of the center conductor fingers was broken, and even though I have GR-BNC adapters, it's more useful to me with BNC, so I replaced it with a BNC by using some suitably sized washers jammed in the panel-mounting hardware for the GR connector.
Bought a car does that count?

That's not a car, it's a Jaguar
Enjoy!!!

Nice, she is in really good shape. What year is your kjs?

Yeah, until I got these, I was unfamiliar with the GenRad style connectors. A hermaphrodite RF connector - it's a very clever design. I don't have any, and of course a few hours before buying the Tek pieces, I bought the other connectors, attenuators and whatnot from a guy at the swap meet. In conversation, he mentioned having gotten a bunch of the GR connectors from a surplus place in San Diego that had closed. If I'd known I'd be getting the Tek generators later in the day... Oh well. I figure I'll look into replacing them with either N or BNC jacks, as I can easily get adapters to whatever I need for those.

Well I bought it 2 months ago and it finally arrived!
...on it's first charge right now

Oh boy...I hope you don't go crazy...I rented a Flir sometime ago and ...went crazy...good thing I had to return it
Who can't use another power supply? This was an impulse buy 800W Xantrex XTR33-25. Clean and fully operational for $75 shipped. There are no better power supplies than XANTREX made by real Canadians.
Funny, one of my recent purchases is a Xantrex power supply and it oscillates like a guitar string
It's really too bad, I bought for the GPIB capability and had really looked forward to having a computer controllable power supply.

Looks good Macbeth - what did it cost?
Hope you are you going to post some pics of it in action.
Its IXTN46N50L linear mosfet, planning to use it for constant DC dummy load, mine is used though, new at Digikey cost $42 a pop.
500 volt mosfets...
I've been thinking for a long time about taking four of my IXFN200N07's and screwing them to an old CPU heatsink and fan to make a 200 amp H bridge. Thing is, I don't really need a 200 amp H bridge for anything right now.
I still want to try it.
Building a dummy load would be a better project. I suppose the IXFN106N20's would be better for that since they are 200V. The 200N07's are only 70V.

£199 from Amazon. I tried shopping around and even using flubit for an attempt at discount but no chance. Originally given a one month lead, that passed and another month added on.
Clearly selling like hot cakes - they could charge a fair bit more if they wanted. I think FLIR have been taken by surprise with the sales of the android version.

1990 with 40k miles in almost perfect condition, except for the famous Jag oil drip

Isn't that a standard feature that comes on all of them?
Sharp looking piece of machinery. I hope you can house break it.

Vehicles that look that good are allowed some quirks.
It's just marking it's territory
Not a purchase, but a dumpster find: Acer H5360HD Projector. Looks like new and all the major bits work, just the remote is faulty. No it's not the batteries, it's not transmitting anything, which is an issue with this model because there no control buttons on the unit itself.
Not sure what I'll do with it when it's fixed though.

You might be able to find the IR remote codes. Or get a new remote.
I'm hoping it's just a bad connection or a dodgy solder joint, but the remote seems to be cheaply available on fleabay if not.

Most IR remotes that go faulty, the LED has lifted from its pads and just needs re-soldering. A quick test for IR remotes to determine if it is faulty rather than the receiver is your phones camera. If you see the LED lit up on the phones display when pressing a button the remote is most likely ok. I've had remotes with a permanently lit LED as a fail mode, but most often it is just extinguished.
Yes, I already did the phone camera trick. The IR LED doesn't flash. Inside is just the typical µP with a transistor / resistor to drive the IR LED. The LED looks well soldered, but I'll connect a scope later to see if the transistor is still doing its stuff. There's not a lot more that can go wrong really.

Just watch out - the main camera lens in an iPhone has an IR filter so this test will not work. The user-facing selfie lens will work okay though.
Oooo, didn't know that. I was using a HTC, but I'll check it again anyway.

Finally got my hands on one of these puppies so I can better calibrate & validate my Precision Digital Voltage Sources (vrefs).
From Germany (I'm in UK), refurbed & calibrated prior to delivery to me. Just got her powered up a couple hours ago. Awesome.

Ian, we'll expect to see some videos featuring that new DMM!
