So let me start off saying I HAD a working Mac Color Classic. I had already repaired the board and replaced its capacitors last year. This week I was going to finally recap the Analog board. Well once I did theat the unit would not boot and had a constant high pitch chirp. After care ful examinging of the board I found two issues. I replaced a 0.47 100V electrolytic capacitor with a bipolar capacitor of the same value (I installed the correct one). Still a short. I then realized that what I thought was a tantalum capacitor (Judging by its teardrop style package) may not have been a tantalum cap at all. The capacitor CD3 is located at the front of the analog board where the edge connector slided into the chassis, its under the metal shield.
I desoldered one leg and I can get the analog board to power with no more chirp.
Problem is I threw away the original Cap and finding info online is hard to come by. Can any other Mac color classic owner verify what this cap is at location CD3 on the Analog board?
Here is a closeup shot of my analog board with that shield remove and the new capacitor I installed (Like I said I removed one leg to test). What is this capacitor type supposed to be? Tantalums should have a positive designation on the board just like electrolytics and this board doesnt have that. So a typical ceramic?
