Hello, I'm having the exact same problem that Faz had with a Tektronix T935. My oscilloscope is a T932. The service manual mentions to replace C465,C466,R458 to different values. 0.01uf, 0.01uf, 150ohm 3 watts, respectively. I will get to that soon. Unfortunately when the CRT & the Vertical Amplifier printed circuit board was taken apart, the 2 jumper wires from the electron tube that come from the +ve vert. signal from J138 and -ve vert. signal from J148, came loose. The problem. Where do they connect on the electron tube. Which pin on the tube is +ve and which is -ve? I could not see any markings. Please see attached. CRT screen is on the right of picture. Thank you for your help.
