Hi pplz!
new to this forum and already asking of your wisdom!

me and my brother are working on that Kenwood Amplifier someone got him and it seems that theres a burnt (shortened) transistor or well...what'cha'ma'call it

it looks like a black small chip 2 cm x 1 cm with 5 legs coming out
the marking oh the transistor says:

[B]Kenwood TRAITR[B]
[B]P4Y[B]
[B]7531[B]

now my question is : where can i get that part, I'm kinda new at this and internet gives me Kenwood parts as "like" faceplates and such.

may be any of you know how this part is properly called so i can address someone with more accurate information

thank you in advance.
mafiosy.
P.S. trying to put a picture , dont know if it will work...

Check www.kenwoodparts.com

I don't know if this is what you need or not, but entering 7531 as a part number returned this result http://www.kenwoodparts.com/parts/search.php The next to last part seems like a possibility. I have called Kenwood before and talked to someone who gave me the part number from Kenwood Parts so I could order a replacement. Good luck!

I’ll translate a bit from here:
http://www.audio-muziek.nl/audio-o1/okenwood7090.htm

The TRAITR transistors stand for: Thermally Reactive Advanced Instantaneous Transistor. The two extra pins are used to control the build in bias sensor that would be able to act faster then a normal sensor on the heatsinks.
They are produced exclusively for Kenwood by Sanken.

There is a good chance that only Kenwood will carry them so no need to ask your local parts shop.
Call Kenwood and give them the type number of the amplifier. If you’re lucky they’ll send you the parts.

Hi,

Anyone here have the service manual for Kenwood KAF-3030R amplifier? I have tried asking from Kenwood service centre but they're not willing to release it.
