Are there any capacitors inside the High Voltage cage that you might have overlooked? Also the resistors and capacitors in the Yoke cold be causing problems.
A bad Flyback can also cause this as can a bad horiz output tube.
The white areas twinkling is a separate problem I suspect, does that go away if you turn the brightness down?
White objects taking on a silvery appearance when the brightness is turned up high can be a sign of a weak CRT.

No on caps in high voltage cage. I was wondering about the 2 +3 kv. caps mounted on the fly that are part of the yoke circuit.
The flyback tests good as far as resistance tests per diagram.
The crt has brightness to spare. If I turn up the brightness all the way the picture will almost go completely bright to where you really can't tell what your watching.
The tubes have all been retested and are good.
Resistors in the yoke: I am not sure how to access them.
There is a horizontal stabilizer adjustment. in that small circuit are two paper caps that I have replaced. Could this adjustment be "out" because of slight capacitance differences with the new caps?
