This amp is using P60NF06's for the power supply fets with 47 ohm gate resistors.
Is there a good sub for the P60NF06's? |

The stp60nf06 is readily available. If you don't want to use them because you'll have to order them, list what you have on hand.

Im checking the power supply drivers .
The MMBT3906 (2A) reads 52.4 ohms from collector to emitter. This is out of the amp. Defective? |

If it's similar to the massive and the transistor is marked 2T, it's an MMBT4403.

ok guys i got some of the smt's from a donor amp...it seems one is npn and one pnp since the amp has a mirror circuit on the other side any ways long story short i started her up with one output fet in each rail and it powered up fine and played an eight ohm load on low volume so now all i have to do is get the irf640 and i should be ok.
thanks a bunch for your help guys i'll be back with a fosgate thats driving me nuts. |
