[TechnoTools]

my rockford fosgate t20001bd have blow a mosfet to274.
where i can find spare parts?

rockford says me that its impossible.

where i can buy the component?
i'm in italy

thank you very much...

You are making too much assumptions too quickly. How do you know that only a single MOSFET is blown, and how do you know which one is blown?. When one MOSFET fails it usually becomes shorted and causes maybe a dozen parts to blow.

Also, TO-274 is not the name of any known popular package, do you mean TO-247? What is the part number or whatever is written in the transistor case? Does it contain any logo? (also useful to identify manufacturer).

yes the package is 247...
the component is damaged...

there are 4 mosfet..
two are NPN and two are PNP (i believe...).
one of these MOS is damaged....

the only logo that i can see on it is a great F. its impossible read other informations becouse the component is damaged
i can read the other similar mos.
i not believe thet F is firechild becouse i have already researched the component in the web site....

can you tell me where i can buy it?

thanks and excuse me for my english.
it s not perfect.

Have you tried asking your questions on Rockford support forum?

It seems that you don't know much about MOSFETs and amps and repairing it on your own can be quite a challange.

rockford says that is not possible buy spare parts.... is it possible?
tomorrow i ll read the number of Mos in another amplifier t20001.

PS.

my amplifier now is working but i want change the damaged component before is too late....
for this reason i'm sure that the component is the only damaged on the mainboard..

with the tester i have measured it and the other similar on the mainboard.
the two mos are equal. the other two Mos have different values
