Pin 8 is still at 11.90 volts on both lm5110's

Do you still have a square wave on p7 of U301/2?

 

[seankane]

I changed both LM5110 because one had significant voltage on the output pins.


The amp now draws 7 amps of current and plays clean audio.


I think it was a combination of the HC74 and the LM5110's.


Thank you for all your help Perry.

Don't forget to remove the resistor if you haven't already done so.

I did, thank you.


I changed the LM5110 that had voltage on the output pins, the amp was still lacking current draw but did produce distorted audio. Upon changing the second LM5110, the current draw was normal and clean audio.


Also the rail voltage has equalized on the red and blue wires, and has dropped from 140v on one wire to 125v across the wires.


Thank you again for your help.
