    100W Audio Amplfier By Smart Kit

    I just want to confirm that when i apply the 1 ohm in parallel with 0.47ohm . it will not heat up and i can set the pot . because i have tried a DC millimeter but it didn't give any reading and it's fuse was broken . this can mean there is alot of current flowing through 40V lead

But what does...

But is this...

    The Power Supplies neutral rail is getting burned out , not the amplifier's neutral connection. i think that there is something wrong at the amplifier end , but the thing is i have double checked every short connection , only one transtor Q6 seems to be short , but otherwise i have checked the...
