There's a version of the ubiquitous German halftrack of WW2 called the LWS, or Lichtes Wehrmacht Schlepper. I think that was mainly used for schlepping.
My 2465B was really clean. the only potential issue I could see were some green pins on the SMD electros on A5 and (of course) the Rifas on A2 have evidence of crazing. Goddam crazy Rifa, all rolled and ready to smoke. Despite the likelihood of sending smoke signals across Snowdonia I think I will fire her up.
Ha, mine arrived today too
Scored this bad boy on fleabay today for $240 + ~$10 gas money to pick it up.
Also while the screen is bright enough there seems to be an issue with the driver leaking current into some segments, you can see random dots and 4w symbol appear in the photo when they shouldn't. Mine is I think the old version with 34401-66502 front panel.
Anyone knows where I can get a replacement? If only new version of front panel is obtainable, are there instructions on how to update firmware (if that is even an option)?
Yeah, I've seen those dots before and it's the driver. You'll need the same version as a replacement, either from a donor DMM of the same vintage or a replacement panel/driver chip. Upgrading just the firmware in order to use a newer front panel/IC isn't possible that I'm aware of.
2x 10k Log Pot's, 2x 10k Reverse Log Pot's and a knob
Random story.
I accidentally installed a log pot backwards in a headphone amp. In the next revision I put it the right way around.
You know I think I prefered it reversed. It meant it got loud quickly and gave you much finer grain control over how "too loud" it got
I totally approve of this, but make sure to re-calibrate the dial with an 11 max. because 10 is not enough.
Yup! My effing memory is hopeless!
Lichtes/schwere.... there was a little schlepper, the Lorraine, that's it!

Yeah I already opened it up and looked at signals on the VFD, it's the driver. I started a repair thread and listed some options. Your input is welcome

Oh, how sorry you will be, if they do their thing.
A recent purchase from Jaycar: Deoxit. Now in a little anti-spill base I cut from sheet polyethylene foam.

There was a "light" version also, but it would be: Leichter Wehrmachtschlepper.
German has variations on the word light (might want to call it nuances
).
«leicht» meaning light as in not heavy (-> a light meal)
«licht» meaning light as in not dense (-> light hair growth)
«Licht» meaning light as in illumination (-> light bulb)
On the etymology of «Schlepper»
The oldest source I could find on short notice tells me that "sleppa" is an old Norse word for honing / sanding. In the 12th/13th century (maybe earlier) «schleppen» carried over to the German linguistic usage for the act of sanding sth. (what later evolved into «schleifen») and the act of towing something heavy, thus "sanding the floor".
One of the first nouns utilizing the new term was «Schleppe» -> chapel train, that long cloth/rag on a brides dress.
So «Schlepper» means "the one doing the «Schlepperei»".
That concludes my captain smarty-pants post of the day.

Interesting how the word attached to a sanding method that fell out of use while the word didn't. The British Navy sanded the wooden decks of their ships with big blocks of stone called bears right into the 19th Century, though they had such heavy crews that they didn't need to tow it along the decks, which is how I'm guessing it got to be applied to towing something heavy. They had the sailors push smaller ones back and forth instead, I think (they didn't think many of the little details that I find so interesting worth writing down).

in my case they are bass and treble controls, unforunatly i purchase the spline type instead of the D type, the knobs are 5 times the cost of the pot's so i will reorder them with some other bits on tuesday (bank holiday monday in the uk)

Interesting, that similar metaphors seem to have carried over in different languages: Bearing bad news - «Etwas belastendes mitschleppen».
Homology, analogy or convergence? Interesting nonetheless
This has got to be the longest discussion I've ever unintentionally started here.
That being said, here are some better pics of the gear now that I've schlepped it into the house. There are several duplicates, in all but one case the second unit is a parts mule and not complete. The counter side of both of the HP 8443A counter/tracking generators seem to be at least functional, though one is much more accurate.

"Delivery Exception, Animal Interference"
I don't have a dog, a cat, or any pets.
The only thing I can see occasionally on my door porch are small lizards, small spiders and common wasps.
A convenient way of skipping deliveries here and there in order to maintain their unrealistic statistical requirements?

Maybe the delivery guy had an allergy?

National Instruments USB-GPIB adapter for a great deal at a ham swap this morning.
Was a good event, chatted with Paul from Mr Carlson's lab and met Dave from "12voltvids" on youtube.
Also spotted a guy wearing Dave's "I only give negative feedback" t-shirt - I should have introduced myself, sorry.
