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

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.

Good Evening I have a 7704A mainframe that is in need of repair. I turned it on this morning after not having been powered up for about 2 years. The trace was moving around erratically. Then I

Bill, if you don't mind knobs that aren't perfect, I have enough used ones to set up. They may be cracked, have a soldering iron ding, have some paint rubbed off, but they're serviceable. When I

Hello, Would anyone have a vertical output hybrid for a 7844? Tek part 155-0064 I believe... If anyone has a 7844, I can email them the necessary pictorial info where the part is and how to remove it

Hello, if anyone has access to or knows a source for the following 466 parts, I would be grateful: - (2) A&B trigger level knobs #366-1280-00 - (1) B trigger slope knob #366-1278-00 - (1) vertical

What's REALLY bad about leaving the filter out of the 465/475 scopes is when they're used "IBM" style -- rear on the floor while working on equipment. That fan "vacuums" up every dust moozie in

I'm not sure how helpful this is, but the government calibration manual for the TU-7 / 1M1 / 067-0521-00 / 067-0521-01 is available online: https://www.logsa.army.mil/etms/data/A/009074.pdf

Hi George, I think you can get by just fine with the 067-0521-00 manual for maintaining your 067-0521-01. Those units require almost zero maintenance anyway. You will probably never have occasion
