Thanks to everyone, I have just received a copy of the service manual in pdf from a kind soul. I have, in turn, posted this manual at hifi engine for anyone else who might ever need it (registration needed). I'll probably post more manuals at hifi engine eventually, yes, it is a life saver when you're searching for documentation...and, if I get yours, you can have mine, right?
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...
