Jensen XA2125 car audio amp, anyone have schematics or???
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. |
