Andy,
Jim Myers was close on his info, but the CT-27G11U is a little different
than the CT-27G12. R552(1ohm) is the 26v supply resister and D561(part
#AU02) is the diode, the filter is C567(1000m-35v) and the 26v supply hooks
up to pin 7(VCC2) of the vert. output IC. There is also two more caps off of
the 26v line to pin 7, C462(2200m-35v) and C456(.22)Also there is a coil in
the line also, L451. Also make sure you use original Panasonic IC, as
generics will not stand up(been there, done that). Also when replacing the
vert. output always replace caps C451(220m-16v) and C455(100m-35v) as they
can cause output IC to fail immediatly.
Good Luck!
