Still learning some of this cool stuff. I do have a manual for these style chassis, just want to clarify it as it is somewhat sketchy. The mosfet at location q101 is the voltage regulater , correct?.
Also next to the hot , there is a transistoer which I think to be q703 , but it is punched out on the board. What is it's this function?

Thank you.
 
its a mosfet that powers something to do with the pincushion, iirc.

I think i had a u5000 once that had a shorted mosfet in that area caused me to lose all kinds of adjustments (width was too wide, pincushion was horrible and unadjustable, and it would eat hots every couple hours, replacing it cured my issue.

wait, maybe it was q710 or 719...hell. cant remember now.. my story should be here..
