Boost voltage off the flyback is around 750 volts should be 770 volts after a 10k resistor and b+ is 350volts and should be 385 volts. I don’t know if the b+ diodes go weak from age has anyone had these diodes go weak by not putting out the correct voltage and if b+ is low everything else will be low. And the line voltage is 111 volts. Originally the b+ was 375 volts I don’t know why it dropped.
