Well I think it's happening.  We came home from Church last Sunday and the living room smelled like burnt electronics.  I unplugged my MFW and the smell went away after a few hours.  I pluged it back in later and it made it 2 days before the smell started again.  I unplugged it and the smell went away again. (so I am 99% sure its coming from my MFW)

I have had this sub for about 4 years and it has worked great. (and it still works at the moment)

I pulled the amp but I cannot see any signs of overheating.  Can anyone tell me what version amp I have and also what normally fails and causes the "burnt toast" smell?  I am handy with electronics and have done plenty of soldering in my day.

I need to decide what to do with this thing.  Fix it, turbo it, get rid of it, ???











Thanks for the help,

-Eli

hard to tell from the pics, could be a V1 or V2

Take a look at the board that has the red,blue,yellow,black wires on it from the transformer(2nd pic bottom.  look at the 4 mid sized caps, not the 4 big ones or the 2 real small ones.  they are probably swollen and or leaking.  

The directions on how to replace them are out there or email me and and I can send them.

Turbo kits are available as the list has been caught up

The power supply board says "MFW 15 Power V2.1". The amp board says "MFW 15 Amp V2.2". The speaker output leads are soldered directly to the board. Is this a V2 amp? I did inspect all the caps and they "look" fine.

Thanks for the help,

any amount of crown on the top of those 4 caps would indicate they are going bad.  But normally the cap problem results in a hum, not a burnt smell.

Burnt smell might be the output transistors?

I do not have a hum as long as the ground plug is isolated.  (been this way since new)  Just the burnt smell.

Would you say this is a V2 amp?
