Yeah, I guess there are some that are a bit bigger... https://photos.smugmug.com/Electronics/HP-523C-Electronic-Counter/i-vFLhq9S/0/Kc5nXzmJdTGPb8s5LDX5CtmkQg5wsqhpQS35sXFH5/X3/2018070203340573-IMG_7777-X3.jpg https://photos.smugmug.com/Electronics/HP-524C-Electronic-Counter/i-svDGbkN/0/KFDztTJtRjkd...

I'd quite like a better counter than my TTi PFM1300 handheld thing, but it's not something I use often and I don't really have room for 3U, even if is it shallow. It's still smaller than an hp 5245L... :lol: Don't be dissing the 5245L!!! :P :P :P https://photos.smugmug.com/Electronics/Misc-test-equ...

Pretty much any compressor would do. I'd also suggest that you look at the Thermaltronics DS-KIT-1. I'm not sure about availability over on the continent, but it's available here in the US from Amazon for US $315.00, making it over $100 less than the Metcal. The Thermaltronics guys are apparently ex...

Yeah, it was great fun. Shame they went and used a pile driver on a fly.

... I recall the patter about how one had been stored and just needed circuit boards reseated, which begged the question of why he hadn't just reseated them... I love the clowns who say that. Or similarly, "It just needs a fuse." It's an immediate "nope" when I hear that, becaus...

Was it only me, or was it impossible to get into the forum over the last couple of days? No. Definitely not just you - I was getting bad gateway errors and refreshes were taking forever. I almost DM'd you on DIY Audio to see if you were seeing it too, but then decided to wait it out. It seems bette...

Adorable!! On another note, Schottky arrived here a year ago yesterday. https://photos.smugmug.com/Animals/2502-16-Felines/i-b77xzJx/0/KDX94FchKL42frhHM9whJKGFH6VF2Vw9HDBSVqjzT/X3/25_07-10%20Schottky%2006-X3.jpg https://photos.smugmug.com/Animals/2502-16-Felines/i-n57HnBh/0/KKdKr488MLL9LQQppqpd5jrQb...

A piece of good news and a miracle of sorts. After nearly 6 days Motley showed up. Apparently OK. Where he was is a mystery. I will keep further opinions of that whole situation to myself. :roll: I strongly suspect our opinions on this subject would be in line. That said, I'm very happy to hear tha...

Yesterday while at Blondie's daughter's picnic we learned that Motley, Harley's brother, hasn't been seen for 5 days. :shock: That's not a good sign at all and further angers me that they let their cats outside with those traffic conditions. I guess it's a miracle that Dually made it 5 years and Mo...

Very sorry to hear, Mike. Mine are strictly indoor because they're on the food chain here, cars would also be a potential issue. RIP, little guy. Hopefully Blondie's daughter reevaluates the outdoor cat thing for her others.

Widlar was dropped off by my friend's wife a year ago today https://photos.smugmug.com/Animals/2601-18-Felines/i-5mkvcwK/0/KqdKs2tCjj6nJWjgFfJnh6TvKNphXT5DCFKt2PgNj/X3/26_06-24%20Widlar%2003-X3.jpg https://photos.smugmug.com/Animals/2601-18-Felines/i-j5rhqTb/0/L69c2FLND2JWVmww36nQJXgHf7nSQw8zGKHVKLT...

I have a 1727A - it's a looooooooooong scope! (2'/61 cm from feet to face of cover)

There are several Youtube videos extolling the inventive engineering excellence of the UK mains plug. If you tread on one, pins upward, in the middle of the night when you are on the way to the bathroom, thoughts of engineering excellence are lost in a torrent of foul, filthy and indeed, profane la...

I saw a few of these over the years on the Bay of Evil, but never bought one. Decided the next one I saw I would go for; it arrived last week. It's nothing more than a metered variac in a Clement cabinet, but is a nice unit just the same. The Variac (a Superior Electric device) is rated for up to 9 ...

Nice score on the test oscillators, and congrats on getting the Ham ticket! The guys at the radio museum were on me forever to get mine; finally took the tests back pre-pandemic and got the Technician and General knocked off. In hindsight, I wish I'd gone for the hat trick, but eventually will go fo...

Not far from the truth. I was sitting in the chair and he jumped up on the arm and looked at me as if to say "why are you sitting in my chair?" Then proceeded to force me to move aside so he could lay directly on the seat cushion. But he was not totally happy with that as indicated by som...

If you ask nicely, he *MIGHT* let you use it, but only to preheat it for him, and he'll expect you to move when he wants it again.

Thanks for that. I'll look into it. I was aware someone had brass gears made a few years back, and for a time sold them on ebay. They were $200 as I recall. When the HP 8640A began to play up because of the disintegrating gears, I bought a Marconi 2019 from Stewart of Reading and I like the push bu...

I decided that rather than reverse engineering and dinking around with the charging circuit that I'd just get some 1/3 AAA NiCd cells and make up a replacement battery assembly. Ordered them on the 15th; hoping they get here some time this week. Dismantled battery compared to AAA cell: https://photo...

You lucky thing. Looks like a very nice piece of kit, if rather large. My E4420B (2GHz) generator is a little bit smaller, being only 3U high, but makes up for it by being very deep. Thanks! Yeah, it's definitely a big honker - about 81 lbs/37 kg and 24"/610 mm deep. I felt bad for the poor UP...

Yeah, I need to open it up and dig further into the charging circuitry - the original battery was a NiCd, and I searched on the part number (N-50SB3), and that's the one that came up from Battery Mart as a replacement. https://photos.smugmug.com/Electronics/HP-8664A-Synthesized-Signal-Generator/i-tm...

Took a chance on a pig-in-a-poke on the Bay of Evil and snagged an 8664A 0.1~3000 MHz signal generator about two weeks ago. Incoming inspection is of course a requirement: https://photos.smugmug.com/Electronics/HP-8664A-Synthesized-Signal-Generator/i-KKGw4QK/0/NDJbNQ5SdPmqxM8Zfq9Fs2Hbd6NzSDSmXXzW7kp...
