In the event, it was pretty easy to put the bands on. You can tell when you have it right.
And the 21FAP4 is working GREAT!!!!
As I said above, I removed the rivets that hold the disc on the CRT socket and that allowed me to easily play mix and match. What needed to be done was:
Move pin 3 (G1) to pin 2
Move pin 6 (G2) to pin 3
I can't believe how much better it is. The focus wire actually does something now! I haven't started tweaking it much but the linearity looks better already. Much better detail in credits and stuff with writing. Very, very cool.
I start to think that I might wind up with a good looking, good working Predicta. Been a long road with many mistakes and even a fire but there is hope! Thanks folks, never woulda happened without y'alls help.
EDIT: Guess I better fill in and send the warranty card into Sylvania!!
