Macintosh TV Tuner Card Capacitor Map


Well-known member
I haven't noticed one around, so here is a map of the Macintosh TV's tuner card. The original caps are electrolytic, but the photo shows them replaced with tantalums. All are size B, but you could probably get away with using size C caps. There are some odd values on this card compared to caps found on most Mac MLBs of the same vintage. Also note the little daughter board does not show polarity on the silk screen, so make sure you have a reference handy before you take the old caps off.

2x 0.47uF 50v
1x 1uF 50v
4x 4.7uF 25v
4x 4.7uF 35v
1x 47uF 6.3v
