The old Teks are lovely. My reluctance to invest money in them is due
to the lack of full support-there are chips and assemblies, plus the
CRT, that just are no longer available. For years I've hoped someone
would make replacement CRTs but it's not going to happen.

The new Tek scopes are all digitizing scopes with LCD displays. These
have many advantages but they do not, even with the "digital phosphor
technology", fully replace the analog CRT.

There are many fine Tek scopes out there from about a 30-year period
that are still good to use, and I don't mean to put off their buffs.
But they are just not supported by Tek anymore, and I don't want to
have to look at them when the jug, attenuators, or what have you fails
and it has to go to its final resting place.

It's interesting to note there is a company that-at ridiculous
cost-makes an aftermarket "mainframe" to allow 7000 series plugins to
be used with modern (or any other) scopes.
