trying to get thru a B+ issue thats making me nuts. on the bench, im trying to work the B+ with the HOT transistor disconnected so i dont get zapped. with no load, im getting 160v at the test point, and the same at the Q901 collector. if i load the test point with a 25 watt bulb, its 130, and the pot does nothing. first, is 25 watts enough of a load, or do i need more ? the pot is new, Q901 new, ic601 new. ive checked all over the 600 section, and cant find anything, but i might be missing something. i know there are fake ic601s , but my guy has always been reliable, but who knows. im really hitting a wall here. with the hot connected, and hooked to a crt, the B+ was 88, and not adjustable . the hot and flyback have been changed, no help. i dont see any board cracks, and ive looked hard.
thanks
