Kicker 152x2 Amp problems

[351wcrayz]

I have a Kicker 152x2 Bridged amp, an when I got it the fellar said it had a funky smell when he last turned it on....welp, I cracked it apart an found a transistor or something was burnt, can even see the melted plastic, I will post a diagram later showing the location of the said "transistor" an maybe some can help...really would like to have it fixed....oh well....

Thanks all-
Wes

pls do that. i have a degree in electical engineering so i should be able to figure it out for you.

Ok, heres the Diagramn Dizzal, I know its crude, but it is the best I can do till I get the camera workin, the colors, shapes and everything is accurate, also included orientation too.....I REALLY hope this is enough, if not let me know...


Thanks-

thats one of the output transistors most likely. It can probably be replaced, but most of those will run in pairs, and often if one half of the amp pair fries, it damages the other. You also have to watch out for burned bias resistors in the circuit.

Wow is that all that is burnt? Replace burnt component with equally rated component. Better off spending $0.50 than buying a whole new amp. Plus you won't be out much if you do get replace this and it still doesn't work. Can you take a pic of the insides of the actual amp?

if you have a voltometer i would like you to take readings on the damaged transister and the one below and the one above. tell me the three inputs for each one. if its set up tthe way i think it is the top input to the transister is the output that becomes the bottom input to the transister above. the middle inputs should all be the same. also give me the numbers printed one the traansisters around it.

Ok PD, heres the #'s, from left to right w/ the transistors....

T1-
IRF7Z34
I>|<R 903D
98 40

T2-Damaged Transistor
IRF743
I <|>R

T3-
C25M
02D

T4-
C25M
02D

Thats all I could find on the pransistors, you can use the diagram I provided a while back, the dmeaged transistor is labeled, just go left/right....Hope this gives a bit more insight....Thanks Port Dizzal
