Newer sets used a different brightener since the CRT F ran off the FBT.
They also had isolate only option. There are other tricks on in-lines
that will even help a soft Trinitron jug look better.
There's often a heater series resistor of maybe 2.7 or 3.3 ohms (located on the neck board) that you can shunt. Does same thing as a brightener.
