Panasonic
model CT31SF13U
Chassis ANEDP266
mfd 1996


               Blows HOT (Q551).  Have replaced D552 (RH3F -Shorted) and 
R754 (10 ohm 2W -open)  and rang FBT (73 rings on sencore).
(HOT original was 2SD1556 subbed 2SD1880). HOT will blow instantly.. have 
soddered drive xfmr. Any Ideas??? (what Part did I miss?)  Post mortum 
examination of thr HOT interally looks like too much feedback across the 
damper network?
