Macintosh Plus Display vertically compressed

[keelus]

Hello! I've been working on my Mac Plus for a month and I got this issue out of nowhere.

(The diagonal lines are from the camera)​

As you can see, the display is very compressed vertically, strange display resolution. I tried adjusting the height potentiometer, but it's maxed out, if i turn it in the other way, it goes even more compressed.
This is what I have done to this Mac Plus so far:

• For other issues I had (no display, clicking, and sad mac):
  • I replaced these electrolytic capacitors for brand new ones: C2,C3,C6,C7,C10,C12,C18,C24,C27,C28,C30,C31,C32,C34,C35,C38,C39,C42,C45.
  • I replaced the U3 optocoupler for a 4N35.
  • Brand new RAM (x4 256k)
• Trying to fix this issue:
  • LM324N - Brand new
  • Q3 (2N4401) - Brand new
  • Q6 (2N4401) - Brand new
  • Q4 (MPSU51) - Brand new
  • CR15 - Brand new

I need help to fix this. Does anyone went throught this problem/know what could be causing it?
Also (might be a dumb question), if I buy a different potentiometer to control the height, could I make it stretch a lot so it matches the correct vertical height?
Any kind of help or suggestions will be appreciated.


Thanks for your time,
