analog board

Howdy! I’m looking for some advice on fixing a G3 AIO “Molar Mac”. If I disconnect the CRT display cables from the wings card then it’ll boot perfectly fine with an external screen. However if i try to use the internal display then it doesn’t work. On start up there’s no chime, no LED, but...

Hi all! I am working on restoring my first classic Mac, an SE/30. I've started to dive in and have ordered capacitors and such, cleaned it, taken out the PRAM battery, et cetera. I powered it up after giving it a good cleaning and got a relatively dim vertical line. Page 162 of Dead Mac Scrolls...

Brachus has a great recapping video for classic mac analog boards which he cleans in his ultrasonic cleaner after removing the speaker . But I cant find reference as to how he drys them . Just air or a hair dryer ? Any suggestions greatly appreciated !

I opened up this Macintosh Plus today and came across this mod - never seen it before! Anyone know what it does?

Hey everyone, hoping someone can give me a steer on a problem I am facing since recapping my Colour Classic Analog Board. It was working OK beforehand, but I decided to do some preventative work on it and replace the caps. After recapping all recommended caps (as per the Recap-A-Mac guide)...

I have the typical burning resistor and pair of diodes on my Color Classic analog board (photo of problem area provided, with resistor and diodes circled in red). 2 of them, actually, same exact issue. They both work, but I'd rather not push my luck and fix them while I can. Can someone please...

I was running a longer duration test of my Mac Plus (with 030 accelerator) and came back into the room to find the picture was gone and replaced with diagonal lines and the image was stretched beyond the edges of the CRT. I tested my voltages and they are stable and within spec on 12.0v and...

Hello! :) I tried to find if there was a thread already here on Tinker Different about this but have not. Some people did talk about it elsewhere, though. So, here I go. I understand that many like to keep the Compact Macs the way it was back in the day. On the other hand, I want to give them...

Apart from removing the speaker is there anything else that should be removed before I give the Classic II A/B a bath?

Anyone else have extreme difficulty removing the Color Classic analog board after all cables have been removed. I watched @Branchus' video on the removal and his slides right out. Is it possible the edge connectors are fused somehow. I've used a good amount of force and cannot get it to...
