I have a Macintosh Classic analog board with (among other issues) a damaged RF2 resistor (see picture). I have recapped several boards already but I am not familiar with resistors. Can someone help me identify the right replacement? It seems to me it is a 2K Ohms 5% resistor. Is it a metal film...

So after a few weeks, I found the time to resolder some joints on the analog board (namely, the flyback, the logic board connector, and the CRT connector), even if they looked fine to me. Problem solved! Thank you for your advice.

Thank you for your suggestion, I'll reflow the non-capacitor components on my analog board. Unfortunately, I don't know how to measure stability and HSync and Vsync frequencies, if you have any link or pointer it would be great.

Thank you for your answer. My problem is not as dramatic as what you can see in your video. It's more of a pulsating effect, that becomes more evident when I decrease the luminosity. I'll try to capture it on video if I can. I measured the voltage at the floppy port and it is 5.048v and -12.051...

I got a broken Mac Plus I repaired. Just connecting the power chord (without even turning it on) used to make the main electricity switch trip. I recapped the analog board, replaced the optocoupler, recapped the logic board, and added a diode in the empty location on the logic board to provide...
