bump! just got one that i'm trying to fix up for a friend, i think it is missing one of the lamps? also, not sure how all of the photo resistors are supposed to be oriented in order for it to work correctly. I can post a shot of mine, but I'm not sure it'll help since it may be incomplete...
take a look on "the other forum.org", there are guts of a couple of PFA, which is the phaser with no volume control. the switching is gonna be different, but nothing that a good schematic couldn't help figuring out.
Only those who attempt the absurd will achieve the impossible.
