Re: Need some help with an Atari Switching Power Supply

Y'know, I was thinking that same thing. The part originally in there
(probably someone else replaced it) has the diode diagram on the chip like
this -->|*|<-- and it's marked the same as in the schematics and in the
parts list even though the schematic diagram shows the diodes going the
opposite direction. So that really confused me. The part I bought is
FEB16CT. Probably what I need is the same part with the "A" Suffix.

Another Atari Misprint?
