Hello, I recapped a Classic with capacitor damage on the analog board a few weeks ago (logic and analog board). Everything worked fine for a while, but today this pattern appeared on my monitor. I managed to narrow down the problem to the analog board (I swapped it with another one and the Mac...

I have a Macintosh Classic that a few months after recapping (and replacing diodes DP3 DP4, the optocoupler, and the TDA4605 chip) started exhibiting a wobbling in the lower bottom of the screen. The wobbling disappears gradually (line by line, from top to bottom) as the Mac warms up, taking...
