I just don't understand why anyone would want to have scandoubler/flickerfixer for A1200/A4000/CD32???
Just buy one of these http://amigakit.leamancomputing.com/...roducts_id=226
and LCD-TV to get nice flicker free hires picture.
Scandoubler is just one more component to have problems. ECS is diffrent thing, it replaces graphic chip, gives a RTG modes etc., but for AGA everything just simplier and more reliable with LCD-TV.
