i know what the problem is. it has a few blown outputs. and the board looks a little burnt...
so you say it still powers up , but it will start smoking right?
i can find the output "fets" for the amp. no problem. they will cost around 4.00 each though. it has 32 of them. and i have to replace all of them. if i don't the amp will just blow up again..all of the 64 gate resistors will need to be replaced also. (and whatever else i find that is bad)
the audio driver card ( the vertical card in the output section) will need to be rebuilt as well. that will cost 50.00. to have it shipped off to db-r, and have him do the work. i dont have the equipment.
me and chris have been friends since 07. he does good work. he just hates to mess with these "big" amps. i am just about the only person who will repair them. (or at least try..lol)
32 outputs - 4.00 each plus shipping = 135.00
1 driver card rebuild = 50.00
labor is going to run around 225.00
guesstimate- total with return shipping is going to be around 435.00
this is cheap for a repair this big. and it is a beast to get out of the heatsink ,let me tell ya...lol..
after im done ,i will have replaced almost 100 parts inside the amp. i wont do repairs any other way. the parts need to be replaced to make the amp more reliable after the repair.
