Hello, I'm back to working on my old Scope. I Made a lot of progress from when I last touched it.
(Preface)
I ended up reseating every tube, Inspecting the top to see if it turned white and dusted it (SilkScreen is still intact). I went back to my last forum post and read all the suggestions and Replies that I got. I started with checking the -150v rail with my multimeter and adjusted it until it was 150 and all the other rails where Fine, Next I adjusted the high voltage to 1350v. I got my other scope set up for reading high voltage and checked chassis grounding. I managed not to blow up my other scope and did some troubleshooting of the power supply. The Test Point (6.3 Not under ELEV .225 bracket) has ripple (+/- 10V). (Other then that everything works except my issue)
(TLDR. Rail Voltages are in Range (-150,100,225,350,500,-1350), Rails has Ripple (+/- 10V)).
(Repair Help)
The issue that I'm having is that the vertical of the CRT Is causing the Trace to go off the CRT. I thought that there was something wrong with the CRT Because there was just an Moving smudge. one time I started the Scope and the trace started at the bottom of the CRT as an smudge then an trace on the screen that started to move up the screen and then going off the screen at the top. Turing into another smudge.
After that I unplugged the upper and then the Lower CRT deflection plate (One at a Time) and got a Good trace with the horizontal sweep working Fine along with the timebase. The issue is that I don't know why the vertical don't work properly causing the trace to go off the CRT.
Everything on the Surface seems fine (Minus the Ripple) but I have some suspects I think that either the vertical amplifier or the type CA Plugin is faulty. both look visual fine (Tubes aren't cracked, etc) the issue is that none of the pots (Vertical Position & Vertical Position Range control on the ca Plugin) have no effect. The other two pots on the vertical Amplifier have no effect either (GAIN ADJ, DC SHIFT).
TLDR. Rail Voltage is fine, (+/- 10V) Ripple On Rials, Visual Inspection is Fine. CRT Vertical is Faulty making the trace to go off the CRT. I Unplugged the Vertical Deification Plates and everything was Fine. Vertical POT's have no effect on trace Position, Vertical Amplifier and CA Plugin are my main culprits.
If anyone has any suggestions/ideas/help then it is greatly appreciated. Thank you in Advance! (Images 1,2,3 are what happens on startup and #4 is with the vertical deflection plates Unplugged)
