Hi. I have a Sansui 5000a that has a power issue. When powered on through my dim bulb tester, the light bulb stays bright, indicating problems. But when I remove the two speaker fuses, and power on with dim bulb tester, the Sansui powers on, and DBT, bulb dims, which is good. So I’ve went over the Ripple board, all good there. Pulled output transistors, they test good. Check diodes. So, I now will look at the Driver boards. Am I going in the right direction? This 5000a has the notorious F-1040 driver boards. Ugh... lol. Also, two of the big 2200uf filter caps measure more than double spec. Each Like 4800uf. That measurement taken with caps connect in circuit . The other two measure fairly close to spec.
