Hi all, I've recently purchased a 7A16A, working, looks new, S/N B138015. Probably the previous owner has tried to calibrate the HF response in a badly manner: risetime was 3 ns with very rounded fron

Hi all I have a loose 604 crt so I thought I'd ask on the offchance that someone has a 604 parts unit - hopefully lacking little more than the crt, but ideally including the power transformer and supp

Hello, I joined this group after purchasing one of these scopes which arrived defective. Originally, the low voltage power supply was ok but the high voltage supply had a problem where the fuse was bl

I'm ready to part out a 5440 mainframe to clear it out of my workspace. Everett, WA 98203 It powers up, but I don't have an amplifier to test anything. Based on the state of other gear I acquired in t

Starting a new thread as although this is on the same scope, this is a different question and I want to avoid another long thread. I looked in the 455 service manual and in the Tektronix 'Troubleshoot

I just finished replacing the Battery, rebuilding the Power Supply, broken Scale illumination Pot on a 2465A for one of my nephews. It had an SRAM Failure that I had to replace. The Failure was intern

I have a Curve Tracer Adaptor, P/N 013-0128-00, for a 5CT1N/7CT1N plugin and a previous owner removed the larger of the two sockets (for a TO-5?). From the documentation I have, that socket is P/N 027
