ROCKFORD FOSGATE PUNCH 301M

Well, another amplifier to repair.

For the opening, I found, Q7, Q15 and Q115 shorted too.
Q7 and Q15 have replaced the IRF3205
But I can replace Q115, Q151 and Q150, for IRF640? (Is that I no longer
540 more are in my closet ....)

R40 I've also found some "toast" and fail to see its value ...
I have the schematic, but also fail to see its value ... (Russian literature is like ....)
Does anyone know?

The 640s aren't going to be as reliable.

R40 is a 33 ohm.

Okay, I'll ask, send me a few 540.
Thanks for everything, Perry.

Well, I changed the three IRF 540, and R40, which I needed.

I connected the amplifier, and, perfect performance!

Another milestone reached, I wish all repairs were that simple ...
Thanks, again, Perry.
