In case you haven't seen it yet, THIS might help.
Good luck.
No I've not seen that yet.
I took a look at it and began the process for troubleshooting the vertical section and the strangest thing happened.
I went to change the trace thing to show channel two and that was when I noticed, it actually showed a trace for channel two. I was intrigued and I connected a battery with some wire to the input and I'm very delighted to say that it does indeed seem to be working now!
I think I know why too. When I had the scope opened up earlier today I was examination the rotary switches used. They are very different to most others and definitely a world different than the rotary switches in the tektronix 2225 tear down video, these are pieces of thin metal that are parallel to the vertical PCB and they are pushed down at certain positions by the rotation of the rod connected to the switch because of bumps on the rod, the only way I can think to explain this is like a camshaft hitting the pushrods, instead of pushrods, its contacts.
Since I found these contacts interesting I sat for a while and just played with the knobs as Dave does. I think that perhaps when the 800volts was applied a year ago that the ticking noise I heard when the cap (the sorce of the 800v, its a long story) discharge might've welded some of the contacts down with some very tiny force and me playing with the switches freed them up.
Either way both channels are now working! The only problems remaining on this oscilloscope are my 1) lac of actual probes, 2) missing clear plastic indicator with numbers on it that should be around the knob of the second channel voltage selector (its not a huge problem, I just have to look at channel 1's knob to see where the second knob is at as a reference), and 3) I do not know what state this oscilloscope's calibration is in.
Any suggestions on how I can calibrate this? The only relevant things I can think of to calibrate it is the scope itself and a 555 chip I have, I dont have a function generator or anything.
