Re: 7704A Repair and modules.
As I recall, the reason Tek would not recommend a 7B53 as a timebase for a
7704 is that it will not sweep fast enough to take full advantage of the
7704's 200 MHz bandpass. Other than that, I believe

Re: 7704A Repair and modules. 7B53 in faster frames
Yes, that's what I was talking about... I know it's written up in one of
the manuals or catalogs, but I can't seem to locate it at the moment.
I guess I'm just picky :-) On the other hand, 7B8xs are

Re: 7704A Repair and modules.
There's not a darned thing wrong with using a 7B53A in a 7704 or
7704A. It's the 7B92/A that you can't easily use on lower bandwidth
scopes only because they can't handle the faster sweeps. And

Re: 7704A Repair and modules.
The 7B53/7B53A is not recommended for use in the 7704/7704A. I don't
remember why, but I think it was a good reason. The original poster needs
to find a 7B70+7B71, 7B80+7B85, or 7B92/7B92A.
