Trying to find the right FET to replace burnt up ones with

I'm trying to find a FET for my amp but i dont know which one i need or where to get it. I checked the local Radio Shack. They had some but I'm not sure if they are the right ones. On the board is reads FET1002 and FET1001 they are burnt up. On them is a part number which is 75339P. Then under that reads N2 36 F DN

Hafler use international rectifier hexfets. there is alot of confusion what constitutes a mosfet amplifier.
if the outputs are mosfets instead of bipolar transistors, it is a mosfet amp.
some designs are using mosfets to drive the switch mode power supply,but use bipolar output transistors.that is not a true mosfet amp.
you need to go to an electronic supplier for the repair industry.
or the manufacturers warranty depot,who will be able to order them.mosfets are very high current devices,you have to ask ...why did they fail. if they are the switch mode drivers,there is bad capacitors in that circuit

Replacement fet


http://www.mcmelectronics.com/product/483513047059 But this is a transistor NPN and a small one at that for only $1.39. A FET costs about $35.00. 9322 121 46687 is the power FET for that set. Location #7301 Description STW13NB60. http://www.partstore.com/Part/Royal%20Philips%20Electronics/Philips/932212146687.aspx IS one place, or Google your part# and see what comes up. Hope you find what you need. Good-Luck. Let me know if you need something else.

1: In most cases there are two FET`s gone you can use a normal IRF 530 but cut the heat sink from the FET do it with a pincer not with a grinding machine! (static electricity!). Before you switch on the set pay attention for the following parts!
2: The two coils that are mounted under the metal housing on the main board look of they have a other color if so they are burnt Check also the SMD parts under the main PCB.
3: The two SMD Elco`s that are mounted on the little PCB they have in most cases a high ESR. The value must be under 1 I thing that all the troubles you can have with this set are coming from this two elco`s (100uF 16 volt.)
4: look for a short cut on this little PCB pay attention to the two SMD gates. Measure the S/C over the +5 and +12 volt lines and check both PCB visual.
5: You must bring in a lot of heat to remove the both IRF`s use a good flux and do not fear the heat they can have it.
Because you must use a big Iron there is the danger to damage this aluminum layer check visual after you have solder the two FET`s all the connection with the smaller parts measure them with a Ohm meter. This was the fault in mine case there was a open connection to one of the gates of the FET`s

Blown amp


hi, try connecting the power b+ and gnd and remote turn on cables only (dont connect rca input or any spks), if amp doesnt turn on you will have to take in for repair. no need to buy new amp, coz problem could be a burnt pcb track or even a faulty remote or FET circuit.if amp turns on then connect other cables slowly and monitor the power lite as you do connections. you may have a faulty spk load that will cause amp to stay off or in protection mode. cheers
