does anybody know where i can get a scematic. i need to know what part # to get for the power supply drivers (Q901, Q902).

thanks

I don't have the manual. Are there any markings or numbers on the drivers?

 

[bdgf2004]

on 1 of em i can see BA. sot-223 package.

 

[Perry Babin]

Are you sure it's the SOT-223 package? I don't see one with the marks BA.

 

[bdgf2004]

same type of package but a little bit smaller.

 

[Perry Babin]

If these are PNP drivers, look up the datasheet for a 2SB1260 to see if it will fit.

 

[bdgf2004]

spec sheet says its the same size

 

[Perry Babin]

It should be a good sub (assuming that the originals are PNP transistors).

k. i got my new dvd and board today in perfect condition.
thanks

Well... now you can't say you don't have anything to do.

Has anyone tried this sub? I need to replace the drivers in this amp. Is there anyone following up this post?

Just answering my own post this is the original transistors Q901/902

ROHM|2SB1132T100Q|TRANSISTOR,PNP,32V,1A,SO-89 | element14 Australia

That should work.

If you have any more questions about the repair of your amp, start a new thread.
