directed 1500d

[mike49504]

Im working on this amp and the outputs are shorted. My first question is they use irfb31n20d in the outputs is there a good cross for that part or do i need the same part number?

Second question is Wondering if the 1023's and the1027's in this amp are the drivers for the outputs? Since one side of the outputs get red hot

Check the drivers (Q15, Q16?) and the gate resistors also.

For the originals:
2sa1266 - Octopart

For subs:
511-BD140 (mouser) or a 2N6491 (installed facing the opposite direction) if the holes in the board are large enough for the legs to fit.
