Hello, quick question. I am looking for an equivalent Transistor for a 9Bt. Not been able to find anything of use online, therefore I m reaching out to you all. I have found this 9bt is a MMBTRA109SS.
Thanks for looking and assistance. -
Hi Guys,
I am currently working on fixing an active subwoofer and found 2 bad transistors. One is A965 and the other one is C1815.
C1815 is easy to find but A965 not so much , at least where I live (Romania).
Can anyone help me identifying an alternative / equivalent for this , A965, transistor ?
Is there an online tool / engine that I can use that could help in this ?
Thank you

Hi All,
I have a 30+ year old Marantz PM310 that is blowing fuses. It appears that one of the output transistors (Q732) is shorted (Q731 is fine). It's a 2SB633 which does not seem available from the usual suppliers. Is there a more modern equivalent which would do the job?
The complimentary NPN (Q729 & Q730) is a 2SD613.
I have attached the service manual.
Many thanks.

Hello
Got this speaker from a friend , defective. Power led comes on and off , in a loop.
Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.
I tested powering it up without the IC, and the speaker turns on and stays on, and works fine
Still, I need to replace this transistor.... -
hi people, i need some help to identify a transistor(q14) that is missing on the board, so the gpu has no voltage i think that q14 activate the phases for gpu, but i dont have schematic or boardview, but i think its the same transistor than q15 and q16, thanks...
