Not in the best state, came with wrong mouse, an ADB one, apparently turns on but nothing on screen. I'll add photos when on computer.

The logic board looks good, analog board I didn't look at too long, Ill take a closer inspection tomorrow afternoon. The system appears to make a single pop noise and a very faint whine after that, no chime, no screen.

Update:

Complete analog board electrolytic cap replacement with 105C ones, including PSU resulted in the same issue, at least that is what I thought. The mistake of not messing with the brightness knob got me until 2 minutes after being disappointed, I adjusted it and after a few seconds it showed a cursor in the top left corner and asked for a disk, floppy drive was tested with a 1.44mb disk just to see if mechanism was working, it made reading noises with no unusual sounds and the drive pushed back out the floppy and an X appeared on the screen. I will buy a system disk on Sunday as well as a mouse.

The only issue that I can gather without a system disk or a mouse is that it will only chime through headphones and not the actual speaker.

The only 3 things I will do is adjust the CRT, clean the floppy drive internally and replace the speaker if that's the issue, I'm reluctant on opening it due to the mistake of breaking the neck of my Mac SE CRT by accident.

Ah yes, the brightness knob has nipped me a couple of times, too! Now it's procedure to full twist that guy every time! Good job, nice to see it back to life! Sorry to hear about the SE.

I hope to replace the SE screen and fix its superdrive at the end of November. I forgot to mention that every connector joint on the Plus analog board had the old solder removed and replaced with flux core solder. The outer shell will be cleaned but not retrobrighted. That dent in the corner was real easy to fix too.
