Hi all,

I have a nicely blown Jensen XA2125 car audio amplifier.

6 FZ46N hi speed Mosfets are blown up, and some other identifiable parts (outputs are also
gone, N-channel/P-channel TIP35/36 )

Anyhow, there are two transistors that were removed by the PO that I have NO clue what
they are (cuz they are missing!)

Q203, and Q103. I am assuming that these are pre drivers of some sort on its way to the
output stage. These are one from each channel, so basically, I can't find its mirror
image because BOTH are missing.

Anyone ever service one of these amps? I tried calling Jensen, but haven't had any luck
obtaining schematics. I'm sure the shop that started the repair had a refused estimate,
since 6 of those output transistors would have been quite expensive (if using NTE
equivalents). They are reasonably inexpensive from digikey, $2.00 each Canadian vs $13.25
each for NTE equivalent Cnd!!! ouch! x6!!!!


Any help would be appreciated.

Did the Emailed information help? I noticed that I forgot to mention that
Q103 is the same as Q203.

If by any chance you're still trying to repair your Jensen XA2125, I have
one you can have. I'm tired of searching for repair information and/or
schematics, so if I can't fix mine, I might as well let someone else put
it to good use. Mine had water dripped onto the case, which inevitably
condensed inside on a few transistors, which obviously screwed it up. To
the best of my knowledge (without testing equipment), everything is ok and
functional beyond the transistors in the corner where power, ground, and
remote are. It played temporarily shortly after being damaged, but I've
sense disassembled it. I have no intention to check this forum again, so
if you (or anyone who reads this) still need it, send a noticable e-mail
to sdalbert%hotmail.com (%=@). The amp will further remain a doorstop.

Yes, I want the one you have. I will send you an email with mailing instructions. Thank you.

Sorry about the edit, I figured out what I did wrong.
Thanks again,
