Kevin,Steve;I also have a SIDUS,Mod#Sid 1500N,probably the same chass.This
was given to me & had the HOT missing.Can you tell me the # of it?I tryed a
BU2508AF which runs hot & sides of picture are bowed.This one may also have
a weak fly but would like to try the proper HOT before junking it.The fcc#
on this unit is EVOKD-1500N.It has the two 1 K resistors that Steve
mentioned R637 & R638,but could not locate L401 or Q407 that Kevin
replaced.....TIA.........
