Need schematic for a polk psw350 sub

hi there, and i truly appreciate anyones help in this regard. im looking for the full preamp and power amp schematic for a psw350 sub. ive searched here and found on but was different revision. it was 62-0010-0000 rev c. what i need is the schematic for 62-0010-0000 rev b, and there are differences. on mine the mosfets are irf540 and irf9530, where as on rev c they are both irf9530. again if i could get the full schematic i would so appreciate it alot. thank you in advance and i look forward to maybe helping others too........Bill
