JL 500/1 Schematic

[TotalNovice123]

I have a JL 500/1 that I bought to repair, I thought it was just the MOSFETS but it looks like the resistors are trashed as well. I brought it to a repair shop instead and they said they would fix it for $80 if I could find a schematic for it and the part numbers for the resistors as they are damaged and unreadable. Does anyone know where I can find a schematic? Anyone do side jobs and want to repair this thing? 😀

It is a JL 500/1 REV3

If your Rev.3 board looks like this then
Use IRFZ44PBF for Q600 - Q607 like these 844-IRFZ44PBF but you can get them elsewhere.
Use 47 Ohm, .25W, 1% SMT 1206 size resistors like these 652-CR1206FX-47R0ELF but you can get them elsewhere.
For Q608-Q611 follow this link http://www.diyaudio.com/forums/car-audio/121433-jl-500-1-smd-transistors.html#post1485563
I have not had to replace R654 or a D600 are you sure they are defective or are they missing?
