I am so fucking pissed off at the moment. Did a 50 mile round trip to pick up two scopes and the capital toss wank had already sold them.
Alas two nice big Telequipment D83 mainframes are not mine
Yep, that would get me going too.
Bloody nice scopes they are too, a poor mans Tek if you like.
By the time the D83's came on the scene Telequipment was owned by Tek.
If you get one sometime I've got some cross/ref files, manuals and notes I can send if you want them.
Indeed. My mother actually worked at the Telequipment factory back in the late 1960s and early 1970s on the production line as well so there was some sentimental value at least.
Wow, nice bit of family history.
They are marvellous scopes for the money. They actually have the same tube as the 7603’s but without readout and not quite as good a final amp. Can still get differential plugins as well. I owned a D83 for a couple of years around 2000 that I paid £5 for so I was hoping to get rid of sellers remorse a bit
I'm remorseful too, it was my first scope and despite it giving me a good amount of grief I learnt one hell of a lot about CRO's keeping it going. I got it pretty reliable then like a mug I sold it when I got my first DSO, a Tek TDS2012B. I bought, fixed and traded CRO's for a while before Siglent days and none had such a nice display as a D83. I reworked most of the 2750V EHT and the traces were soooooo sharp and clean it was delight to use.
I do hope you get to stumble across one if only for mums sake.
Anyway I shall not lament that loss any further.
I will take you up on any documentation offers if I get my hands on one again - thank you appreciated.
The plan was to refurb one working unit and then develop a custom pair of plugins with an HF band spectrum analyser based on the numerous ARRL / W7ZOI designs out there.
When I was given mine (broken)
there were zero manuals online and I had to get a paper copy from a guy in your part of the world and ~20yrs ago and I was as nervous as hell about online payment but my cousin was in London working and she popped over and grabbed them for me then posted them back. Sadly they went with the scope when I sold it
because by that time manuals were available free online but a little tricky to find so I uploaded what I had found to the EBAMAN repository where 2 parts of the D83 manual still are. The third part I still have in my archives and I should retry uploading it as I how have much better internet connection than I had back then that gave me gawd knows how much grief at the time.
The crossrefs I have are for the many unobtainium transistors and with an EE mate checking my substitution choices I made a list of easy to get equivalents.
Crossref attached as a teaser.
See if you can make sense of it.
The 3 other manuals are 14, 15 and 19 MB that cover the D83 MF, S2A dual sweep and V4 dual trace amp.
I whipped up a extender cable for the plugins.....this I still have but it's piss easy to make one if the IIRC .15 pitch card socket is available along with some PC IDE ribbon cable and a strip of blank SS PCB with fingers etched to the right pitch.
Just PM me your email and I'll shoot it all through to you. No catches, no BS.
