Is the Y scaling per small division (+/- 5 within the box) or something else? Either way it doesn't look like the -5V is decaying to 0V and is Ch3 inverted? There is a very clear signal on LIMIT which

Hey Tony, welcome to the group. I watched the videos you posted in another thread detailing your 2465 CTS troubles < https://www.youtube.com/watch?v=oxZZ7-VjCQ0&t=1s>. Here's my advice for how to

I have a 551 and 535a I'm working on restoring. I want to use them especially on tube audio amplifiers. My thought is if I mess up and expose them to high voltage they're likely to be more forgiving

Tony, Clean the beam find switch. If the contacts are dirty, all kinds of strange problems can occur.

Some space heaters eat up a lot of electricity like that too. When my basement lab gets cold, I have this cool retro-looking space heater, a model Tektronix 547, that takes the chill off. Best part is

Hi Roger. Reminded myself how to add photos and have uploaded three tonight that should help answer your queries. They're under a new album with the same name as this post thread. The 'white'

Sorry for the typo, the correct number for the cable is 012-0482. Jack

Please start a new thread about this - IOW please don hi-jack threads. David

Hello All My SG503 front panel specifies a slightly different cable number - 012-0482-00 ( I do have one of these). Not sure how this differs from the 012-0480-00 but it does have a metal rather than

I'm new here and I'm looking for someone to help me with my Tektronix 2465 DNS (aslo known as 2465 CTS ) I made few videos here: https://www.youtube.com/watch?v=oxZZ7-VjCQ0&t=1s about my sick scope.

I have the same oscilloscope. It is also listed under (at least that is what I found today) as Tektronix 2465CTS (or 2465 CTS) . Mine has some problems, sometimes I loose the text on top and bottom of

Hello Jared and Rick, Before you make an investment in this enterprise you are considering, you may want to go back to the beginning of these posts from 2015. It was categorically stated the the real

Hmmm, If that's the case, I have a crimper and dies for the high quality Canare brand 50ohm BNC. I wonder if it's worth me making a batch of cables to send out for the cost of parts and shipping if

I may be a little late to the game but I posted this question to a Tek expert on Youtube: https://www.youtube.com/user/w2aew This comment/request might be a little out of scope, to calibrate a Tek

Nearly all of the Tektronix products from the 1960's were a marvel of superb designs. I actually prefer the older scopes as long as high bandwidth is not an issue. These old scopes are generally very

John and others, I have a 547 and a 545B that I plan to run for a long time. One of the two late 1A1 plugins I have has low gain in one chancel. Not diagnosed yet. Have had other scopes of that era

In one of your earlier posts you said you had seen spiking behaviour on pin 3 of U1624. This will drive larger spikes from the output pin via Q1614 and C1602 into the protection circuitry and can very

Took up Fred's suggestion and connected -5V to the power supply board. Didn't crank the supply up high - tried 0.2A and then 0.4A current limit. Max draw was 333mA with all combs in and P1560/1570
