Think they are on the crt board. If I remember correctly those resistors
will have a load path for the 140 volt supply when the set is off.

Hi, thanks for the reply, I don`t find these resistors in my set and I
believe the BG5 & BG2
are the same chassis, where are the "6" series resistors located?? Larry E
