So yesterday I brought home a working Tektronix 2236 scope for free! It lived its entire life offshore on a oil & gas platform (salty air). From what I can tell with limited scope experience, it's operational. The switches and controls are in need of cleaning. So I tried to remove it from the case but can't get it out. It seems to be very tight at the front faceplate end. I've pulled, pryied and hit it from the end. Does anyone know of a way to get it to come out. I even thought of removing the faceplate but am scared of that. I have no choice but to get it out because the controls are so corroded. Thanks, Don

Re: Tektronix 2236 scope
i dont have a tek,
but most scopes either the case splits into top and bottom U-sections or the whole outer shell slides off the back! -
Re: Tektronix 2236 scope
Thanks for your reply stj. I finally got it apart. I used my right foot with a shoe on and pushed from the rear while holding both handle cams. It finally broke free.Comment

I am attempting to test a samsung power supply board to verify the pfc ic is working. I am powering up the board with my isolation transformer. The board turns on fine but when I attempt to connect the ground for the scope probe, it trips out the isolator. I was taught not to 'float my scope' so I am wondering if I should test without connecting the ground lead or would that be asking for trouble? Not sure how else to test, I don't have a portable scope. I could plug direct to mains power but that would bypass the safety factor.

Hi all,
hope life is treating you well.
I have a question, as I am genuinely puzzled.
There is this old Tektronix 2215 scope which has been laying around for some time, that I knew had some issue, but couldn't remember what...
Anyways, last night, I thought I'd give it a look, as space is needed, so put it on the bench and plugged it in.
The CRT had a terrible trace which only filled half the screen and didn't seem to respond much to any of the controls, so I decided to give it 15 minutes to warm up whilst I cleared up the bench... -
I have a 40 volt AC transformer that I put a bridge rectifier on, and I wanted to see the input signal and the output signal on the same screen on my scope, so I set one channel up with the test lead on one side of the input and the ground lead on the other side of the input, then I used another channel on the scope and clipped the test lead on the positive side of the output then the ground on the negative side of the output.
When I connected the transformer to power, the wire that was connected between the ground lead on the second channel and the negative side of the bridge rectifier...
