["John Conti" <contitv@xxxxxxxxxxx>]

al m on this quasar chassis when the abl circuit is saturated because of 
open r374 and coil 351 for some strange reason it shuts down the vertical 
out on pin 6 of ic301 am not an engineer but thats
how they designed this weird circiut to work. it took me hours to locate
