Yea I'm starting to realize that. I have the new diodes in. Still have 27.08 volts DC at speaker terminal. Not shore on what to do. At this post. The two brass color long resistor. Are the post to read the same + and -. Voltage? One shows -114.8 the other one shows 103. No load on speaker terminal

When all the components were installed resistor 4111 op amps ne5534 and the rail caps what the amplifier powered up no load connected I was getting a 108 DC voltage at the speaker terminals once I connected a subwoofer it drew amperage above 28 amps in the subwoofer was pulsing as if it was playing 20hz tone. Very load. Spark came from two mosfet that fell one the high side one the low side and it's also the spark came from the speaker terminal once I was connected the speaker it sparked. It hasn't sparked today so far today and everything's been okay.
The fans come on because there is voltage on the terminals.
Is the LED always half lit or only when there is DC on the speaker terminals?
Are the supply still present (and correct) on the op-amps as well as all of the opto-couplers?
Is the rail voltage still uneven (with or without the speaker load)?
