I had a couple of doghouse blue Tek scopes I gave away to a guy, who
wound up parting them out and building some very crude tube audio stuff
he charged a lot of money for to gullible idiots in St. Louis. That
town appears to be a haven for audio con men.

The old Tek scopes are either too much work to keep going, or have
mostly been used so heavily they are no longer usable. There are no
more parts for DESIRABLE Tek scopes! Tek has not made an actual
oscilloscope in nearly ten years and the last ones (the TAS series)
were crude and nearly unusable.

Large quantities of certain parts do exist-because either those are
the parts that don't go bad or they are for stuff you don't want
anyway.



Actually, old Tek scopes have some great parts that lend themselves to
happy
employment in some really nice tube designs . . . .

Indeed! ;-)
The power transformers from the older tubed beasts are great for
projects,if you can find any info on them,or else sit with the DMM and a
pencil for a while untill you've got it..(a variac is helpful too!)
I scrapped one that was beyond help,along with a HP that I couldn't figure
out,tried/tested everything under the sun,finally gave up.
Tons of good tubes,sockets,etc. in there too!


I've got a Power Transformer out of an old Tek Scope - 545 I think or maybe
an earlier model. The model numbers are all starting to run together in the
ole noggin (hey I'm getting old!) and it's been like 5 years since I had
this thing. Anyway, it was one of the big dinosaurs. The scope worked fine
but I had no room for it, so I stripped it. May have some other parts
floating around too. The transformer does have a part number I can supply.
If anyone is interested, let me know. "I" don't need it. Not sure what
shipping would be, this sucker is heavy. I also have 2 manuals for 2
separate models of the 422 scope - both in fairly decent shape.
