Has anyone produced a site for "work around" fudges for Tektronix
specials.? There must be loads of people faced with throwing out say a
250MHz Tek scope, would consider repairing to continued use to 150MHz
or lacking some of the trigger options, etc based around an
off-the-shelf video amp/ECL package, non ideal SMPS transformer etc

I just communicated with a guy who's going to rewind some arcing 485 HV
transformers. Another guy built his own replacement HV multiplier,IIRC,for
a 2200 scope. I'm sure people have built their own thick-film HV divider
replacements,too.
Also,a guy who claimed to have created a discrete replacement module for
the infamous 2445/65 series horizontal output amp IC contacted me about
evaluating it for him.
(I don't have the gear necessary for any eval.,nor a test-bed 2400 scope)

Other than that,I have not heard of any kludges to replace TEK-made ICs or
other parts.

I'm sure that with today's SMD components,some "hybrids" could be made to
replace some TEK-made ICs,and get reasonable preformance,too.
Some of the TEK manuals used to have simplified circuit diagrams for TEK-
made ICs.

the 2445/65 hybrids would be tough,as they were laser-trimmed to spec on
the manufacturing line.
