Hello Peepz, my car amplifier just went bad on me. It was quite expensive, So before buying a new one, I just wanted to open it up and see what actually went bad on it and bingo! I opened it up and I could clearly see that 5 of my Chips are burnt out. Now here is the problem I am very good with replacing anything on the circuit boards, Soldering iron and all that I excel in that, the only problem is I suck in identifying the chips. Now below i am including the picture, can someone tell me what kind of chip is that? and where i can find it? the #s on the chip are as follows
FW1029
FQP
50N06
hmm they arent chips, they are transistors. get a close up shot of one of them, they'll have a number on them that uniquely identify them - something with a Q or N in it most probably.
I just took the pictures of the bad ones, if you see on the circuit board, same transistors are at the bottom, those are the ones that are actually burnt, because they are BURNT and I mean they are so burnt that they are sticking and peeling off. Yes that bad. the rest of the circuit board is clean as hell. and yes you are right the #s i have on em are
FW1029
FQP
50N06
Thanx in advance, i will also PM ya... i need to get it done ASAP.
YEP you are absoloutley rite, thanx for your help brother... just ordered it.. and overnight delievery was more than the 5 resistors :) thanx a bunch...

ps... all the #s were complete F was for fairchild product #s after that was the production date
line 2 was i forgot...
line there was the acutal part # as you said.... and indeed it was the N channel MOSFET

I see queer has already helped ya out! I guess there arent many electronics engineers out here on this board. If you still need any further help, feel free to pm me! This is bread and butter for me :)
One more thing, do you know why they got burnt? I mean it might be due to some other component, most likely the regulator sending spikes. You dont want to just change them only to get them burnt again. You got a multimeter?
Man this sucks, I wrote you a pretty long PM only to know that your PM box was full, and wheni pressed the back button all was gone ! psshh
anyways i will ask ya here… Well, Soon i am going to replace them. And i am hoping that my amp would work. Let me give you the background of this AMP. Its a 1500 watt AMP made by performance teknique. It was powering up my Kicker solo baric woofer 1000 watt. I guess i was playing it one day on a high note for a while, when this bad boy went out on me.
I openned it up and i could clearly see these things burnt. So i have ordered them and i would replace them soon. I need your input if you can help me to locate regulator sending spikes. How do they look ? do you have a pic of em ? let me know if you do please. If you were in states i would have mailed it out to you, and paid for the return shipment. But i just saw your profile and you are sitting in Rawalpindi . So anyways, Reply here or perferably email me @ “[email protected]”. Thanx in advance for your help

Im sorry, I didnt read your post earlier... I will send you a PM with a detailed reply... Sorry about the full inbox again, getting too many PMs lately.
Its an N Channel MOSFET ... well High Current Transistor if you don't wanna go in details ... you can use IXFH58N20 if you can't find 50N06.
you can order this from RS Components site.

actually i got 50N06.... there were alot of websites.. offering for pretty cheap but most of em wanted me to order 50 or above. ..

Well, I dont think it was the regulator, since you said you played it on a high note for an extended time. Do you know how to attack small heat sinks on chips? If so, that would really help. Normally such equipment has an onboard copper plating during the schematic layout which acts as a secondary heat sink, but you never know with electronics.
^^ don’t even think about attaching heatsink unless you know exactly in what configuration that MOSFETs are connected, not necessarily all drains are connected to the ground, make sure if its common among all or not.. you can do that by checking middle leg of all MOSFETS if they are interconnected or not (just follow the track) … Mind you each 50N06 dissipates about .31W/C, so you need a large heat sink. I can see that all these MOSFET are with Metalic Drain so attaching heatsink would not be a problem… but the thing is you will not find any standard heat sink to attach all these togather, or they were connected to the amplifire’s body??
about your 1st post... The other IC FW1029, is it 8 pin IC?? if it the case then its a simple op-Amp... can you more details like exactly what is writen on it... might tell you some pin compatable alternate.
. So anyways, Reply here or perferably email me @ “
