Re: Tektronix 2465B Vertical Adjustment Amplitude Distortion

Hi,

After a quick look on your video I don't think it's power supply related, because the readout is rock solid, and also channel 3&4 do not show the artifact, however...

Always start by checking voltages and ripple on J119.

After that, I would clean the contacts of the vertical switch U400.

If you have another 2465(*), you can temporarily swap the U400's.

Good luck,

Leo
