i am trying to get this chssis working 100 pecent. it powers up sometimes , other times not at all, when it not working right its B+ is 160v . did a cap kit and bi polars, touched up solder joints and replaced R908. R908 checked out but i replaced it anyway.my question is R908 is that a vital resisiter to operation? also if it tests good out of circuit could it still be bad under a load?
 
If you replaced it with a new one, I doubt that's your issue.

Sounds like you missed a cold solder joint or broken trace somewhere. Inspect the area all around the flyback, as well as all the big stuff in the 900's...
 
c701 had i lifted pad but still had continuty. i solder a cap leg to the next point anyway. had her running for 2 hours and picture looks good. lets see if it will fire up next time i use it.
