Recapping my Amiga 1200. There's some strong opposition against replacing the electrolytics with ceramics. DO THIS AT YOUR OWN RISK! Works for me until now although I see why this may not work very well forever. I DO CLEARLY NOT RECOMMEND DOING THIS. It's an experiment I did at my own risk with my very own Amiga (which would have died sooner or later if the SMD caps weren't replaced).
If you are interested in why I decided to try this, read my pinned comment below. The discussion in the comments is also of interest.
Here's a list of the capacitors I used here:
The SMD ceramic caps (The 100uF 16V are hard to get, you can also use 6,3V but it would be better to have more "headroom"):
pcs. µF V Form Designator
1 10µF 25V ?? C407, Rev.1 Electrolytic / Rev.2. Tantalum
2 10µF 25V SMD C C214, C306
5 22µF 25V SMD C C303, C304, C324, C334, C459,
2 47µF 16V SMD C C821, C822,
4 100µF 16V SMD D C235, C236, C239, C409,
These are the through-hole caps. If you don't want to lay them on the board, try to get less than 16mm in height:
2 470µF 16V RM5 C237, C307,
2 1000µF 10V RM5 C408, C811
The sound quality is gonna improve slightly if you use electrolytics in the audio circuitry.
