How difficult is it to repair a bad channel on a tek 465/475? It is
starting to look like I?m only going to be able to afford a half-broken
scope :(

I don;t know how easy it is to get the components now (are there any
Tek-specific ICs?), but Tektronix published excellent manuals with
schematics, and you have aready-made refeernce circuit in the other
channel to compare agaainst. So finding the fault may not be too hard.

I have those manuals if anyone needs them.

I think this is a pretty good resource for Tek info and help:

I joined it a few months ago (it's free) and found some pretty good
pointers on repairing the sweep triggering of my 466.
Somewhere(!) I have some URLs for places with an amazing amount of Tek
parts. Please note that I've not bought anything from any of them - not
yet anyway. I've no affiliation with any of them either. If there is a
need, I'll be glad to search more diligently to try to find them again.
