Ive measured both sides of the resistor and get 150 v on it. Any way to adjust it down? Its still got a picture, but the hor. Width is half screen, vertical width does not adjust at all. Playing with the h. Hold will drop the voltage to 145 or so, but it loses picture. Any thoughts?
 
3 leg bottle cap side mounted regulator transitors may be bad..
there is not adjusting it.. its a fixed voltage regulator
 
have you capped and re-flowed the chassis.

as chad has pointed out check the VR in and out of circuit.

recapped and replaced the transistors. No change. How is this thing still running? Shouldn't it be in shutdown or burning up something?
