Kenwood L-09M Service Manual?

Thanks Hifigeek, told the tech to check out the output transistors. Yesterday, I worked up the nerve to verify the speaker, and no, I was lucky (there), it survived! One would think that the speaker elements and/or the cross-over has taken some kind of beating?

If you didn't damage your woofer or tweeter there's a chance the outputs are okay. Let me know what the tech finds..

Let me add that I owned and L-07 many years ago and played with the output devices to make in a MKII. I thought the original L-07 sounded better. Both of these amps had issues with capacitive loads and were susceptible to oscillating. Because the MKII versions supposedly had high speed output devices this caused the amp to be a bit more unstable. The culprit was the awful circuit board. Which goes to show that you could have the best design in the world; with a poorly designed circuit board the product will not perform. Also the amp was current limited and bass performance suffered because of it. I loved the packaging of the amp and if you look at the Ampzilla 2000 you notice packaging similarities. That's the only similarity I'm sure...
