hey guys i know i have been a thorn in the sides of some but is there anyone that can lead me in the right direction to get full hv back in this motorola set. i do have limited knowledge of this old stuff but i am trying. after a new flyback i still have low hv and i took each wire one by one off the flyback except the hot cap wire and the hv lead from the damper and there is no change. when i power up the hv will go to 16kv and within seconds it drops to around 10kv and the cathode current is still up around 250ma where it should be at 210ma. i have eliminated the wires to and from the fly and in the circuit , removed the hv reg tube, tried another horiz oscillator tube and checked resistors around that tube socket, and went ahead and got a new yoke really because the old one is falling apart anyway, dried up plastic, and the yoke made no difference either. what could be left to raise the cathode current and starve it for hv. being everything i disconnected it dont leave much more but maybe the drive to the hot for the fly if this is possible, would the cathode current raise up and not have enough hv if the drive were to slow or just not at the right frequency because of a bad cap,and where would i look for this cap if it were a possibility.............
