6100 jitters in Star Wars is normal? that's what someone told me

I have a Star Wars with a wg6100. The display jitters/blinks very rapidly, and the blinking sync's with a whirring sound coming from the hv cage. It's like a 10 second cycle. Whirring/blinking for a while, then the whirring stops/gets quiet, display is rock-solid. Back and forth. Everything else looks great.

After a cap kit and a lv2000 install, there's no change. Also replaced all the transistor sockets on the frame, re-flowed header pins, etc, all the usual stuff.

Someone told me that this is pretty common for 6100's in Star Wars, because they were really meant to run on an Amplifone, the 6100 can't handle the signal that the SW is putting out, 6100 on Star Wars resolution not as good as an Amp, etc, etc.

Has anyone else heard this, can confirm or debunk?

EDIT: I should mention that the monitor was hooked up and was rock solid in a Space Duel cab over the weekend.

Correction:

I sat and watched the attract mode for a while. Turns out this happens when the screen image is more populated. In other words, the less stuff on the screen, the more solid the display. When the screen is really busy, like the directions, that's when it gets really jittery.

Also, the whirring sound is coming from the neck/yoke, NOT the hv cage.

confirmed. When more vectors are being drawn you do hear the monitor change pitch. I don't see any where that you mentioned adjusting your B+ after the cap kit. You need to check it.
I do recall fixing a K6100 one time that had this very light whirring noise you speak of. The monitor has been abused now for about 6 months on location and hasn't had any problems.
Why this noise I have no clue but I personally wouldn;t be concerned about it.
 
on the neck board where the orange wire that comes from the hv cage connects too it should read about 181
