Nice, I'll have to follow along. Wish you were repairing a Tek 465/475, though - that's what I've got spread all over my bench right now with no idea where to start.
Have u joined the tekscopes@groups.io and tekscopes2@groups.io groups?
Oh my. RIP my free time, lol...
Thanks though, I'll bet it'll help. Pretty sure what I'm seeing is a common problem, and posting pix might get me pointed in the right direction.
