First post. Just found this site for car audio enthusiasts. I’m trying to get back into car audio. Been in and out of electronics as a hobby since high school in the 90’s.
I’ve gotten a fosgate 240x2 that’s broken. Upon physical inspection found power supply transistors burnt. I can read a couple of letters just can’t confirm the last digit if it’s a 6 or 8. 50n06 or 50n08. I’ve also got a 100ix I tried to compare it with, but that uses Buz11
Hope to meet some friendly folks here, get these old amps I adore back to life

50N06,
For the most part, in all of the Rockford's of this era that I repaired, I used the IRF3205 with 47 ohm gate resistors. If the drivers failed, The MMBTA06 and MMBTA56 were used as subs.

The model number is wrong on the title, it’s a 4 channel 240x4
Nice to meet you, I’ve been searching the forums and you seem to be the top person that responds.
I’ve found shorts on channel IRF9540 and IRF540. searching the web I’ve found your response to another post about (don't use an IRF540N in place of an IRF540) what is the reason just curious
When referring to a Rockford model, you should give the PC# on the board. Rockford tended to mix and match boards and models.
The N-version caused various problems from minor to so significant that they would cause an over-current trip when the amp was powered up.
If the outputs failed, you need to check the gate resistors, the source resistors and the driver transistors.
