Thanks for the advice on this, it's the first time recapping a board hasn't fixed it for me. The Dead Mac Scrolls mentions that the BU406 might be bad, so I'm going to track a replacement down before trying to find a fly back transformer (another flavour of unobtanium).

Hello. I recently got my hands on a dead Mac Plus (no sound, no video, no nothin') and managed to get it to the point it chimes, and gives a really dim, distorted video output (see attached). I think the LB is OK since I can see the ?disk icon so I've been concentrating on the AB when the...

Hopefully I'll get some time this weekend to look at the beast. Just started a new job and 'spare time' is a thing of the past!

OK, just to complete the documentation on this in case someone if the far future is looking at a similar problem. I recapped the LB (even though the machine works) because . . . well capacitors that old are begging to be replaced. Once that was done, the CD-ROM came back to life!? I'm...

Thanks! Yes, I'm on the rev B board and your advice sounds like a solid place for me to start. Might be time to move it from the 'someday' pile and onto the bench.

Sort of? Resistor RP48 was a charred mess, so I replaced it. The new one died a smokey death too, so there's a short somewhere on the AB (I think), but it's anything but obvious. If I can locate the short, I'm reasonably sure clearing it and replacing the resistor again will fix everything. I...

I considered another kind of CD drive, and just transferring the bezel over, but the bezel appears to be glued on? I guess worst case (if recapping doesn't work) is transplanting the drawer from the broken drive to a working drive, and hope the problem is in the pc board.

Hi! I picked up an imac Bondi Blue this past week, and managed to get everything restored and working (dead hard drive replaced with n SSD, OS loaded), with the exception of the CD-ROM drive. It's D-E-D dead. The drive doesn't spin up, or eject when the button is pushed. Does anyone have any...

I measure the voltages at the port in the back.

What voltages are you getting on the board? Some of the solder joints look a little off, maybe add some flux and reheat them? Is there any audio from the headphone jack?

I thought if you go thru buyee, they take care of the shipping? I found a CCII case on there this morning, but the price is a little steep. Tin's facebook market ad is @...

Ugh! I just saw one last week of sale, but can't remember where! Maybe it was on buyee.jp? You may want to reach out to Tin Nguyen on facebook as he seems to have a tonne of vintage gear.

So the analog board I finally got working a couple weeks ago? Is broken again. I powered up the Classic II this morning, and the image on screen was oversized on the horizontal axis. I tried the horizontal size pot on the back and nothing happened. I expected the size to shrink/expand on the...

Awesome news! Congratulations on getting it restored and, when they arrive you'll have new caps to restore another one (or am I the only sadist who looks to use up all the parts sitting around?).

I would never have thought of the electrolytic goop causing the issue. Thanks, I learned somethin'.

Any time I heard clicking from an AB board, it was because of a short somewhere. The power supply was trying to start, failing, and starting again over and over again.

My AB was only getting to 9.8v on the 12v rail. After reading a lot, I understood that that was not enough voltage to get everything running. I recapped the board without paying attention to the ESR rating, and got the same results. Then I saw a reference to Amiga of Rochester's list of...

Just to close this off . . . I ordered new low ESR caps based on the list from Amega of Rochester (https://amigaofrochester.com/recap-services/capacitor-list/) which I didn't see before I did the cap work. :( Replaced all the regular caps with the low ESR type, and the damn thing chimed and...

Well, the new low ESR caps did the trick! After weeks of playing with this horrible AB, it chimed and came right up. Might help someone else?

I replaced all of them, since I saw that shiny 'hey, I leaked' deposit all over the place. So I pulled them all, cleaned the board and replaced with new caps. I'm going to order new low ESR caps based on the list from Amega of Rochester...
