Rockford 500/1 Outputs

[Tom7227]

I am trying to determine what I can use to replace Q4 -Q7 in this amp. The part number on the output is 50012L8.

I can't seem to find a match for this output.

Thank You 🙂

Could they be BC817?

Correction,

Its a JL Audio 500/1.

Late night, sorry

I thought JL audio used IRF540 and IRF9540, but I could be wrong.

The JL 500/1 uses IRF540 for Q504-507.

I ended up using irf3710Z, they worked perfect !
