"Apparently even Tektronics was not above a well executed kludge." Please stop this. Bad enough in ebay listings, but here?

Wow. Thanks for offering it to the community. Too bad I live a bit north...

The only non-Tektronix scope that can accept Tektronix letter- and 1-series plugins is the Lavoie clone AFAIK. http://w140.com/tekwiki/wiki/Lavoie_LA-265A

Oh and you might want an extender cable too, for when you need to repair it (and you will). I recommend you read the circuit description of the manual and study the schematics. Use this PDF http://bam

Lots of vintage stuff pricing is quite high these days. I also collect 8 bit computer junk and for example a digital doorstop like a Commodore 16 is priced in the 400-500$ US range these days. On the

The 1S1 is a fine sampler when it works. It is however what I would call "high strung". It has a way of failing in interesting and completely different ways all the time. It is also not easy to troubl

Who knows? They're so rare there's not enough data to figure it out. It's worth whatever the two people agree to. If it's local you can avoid all the shipping hassles and that is priceless.

I have a CombBind machine and spines in any case, it's just the odd cropping of the pictures that made me suspicious. Turns out the spine is pretty good and a very clever and handsome person bought th

Well we have the list of checked tubes, I wonder if we have other lists? Tubes are here http://w140.com/tekwiki/images/1/14/157-_checked_and_tested_tubes_specs_and_procedure.pdf

If it ain't got tubes, it ain't for me! Just kidding, that's a good link.

Yeah, I think you're right. But I still want to know what whacky material Tektronix used for that film.

"I even bought a new (old stock) hall sensor (kit) from Sphere but it turned out to be completely useless (much worse than the original)" Did it come with the resistors?

I don't have a print manual in my collection either. Only the PDFs I linked to.

Maybe for driving an x-y plotter?

Does anyone know what is used in the P6042 probe's transformer as the Hall effect sensor? Would a thin film of gold-doped germanium be a candidate?

I think the bigger story here is a 10$ 547.

There are three S-6 operating manuals here http://w140.com/tekwiki/wiki/S-6 Maybe one of these will work for you. I hope your hybrid isn't cracked.
