Has anyone ever seen this prob? I have tested everything according to the service manual. Any ideas..have replaced ic401.h-hold pot,filter,b+ pot ic 601(with known good one). Thanks in advance!!
no inverter board, i never use those..i did fix some broken traces.also previous work had been done and many solder pads were burned off. every part im testing comes back as good..
well i swapped tubes just to be sure and still same thing. h-hold and v-hold adjust does slow the and stop the rolling but the pic is still vey distorted.like trash(noise) not being filtered.there was a cap kit done on it before it arrived, im wondering if i should recap.
ive already have done all the obvious..all the caps were changed. all values are correct and in the correct spot. im just wondering if a cap might be bad.i have fixed many of these but have never seen this issue.
ok, some probs appears to be solved.. it seems the h-center pot was causing one of the probs.i still have to change the filter cap ,so i will give a final update soon.
