Default Musical fidelity A2 schematics

I bought a Musical Fidelity A2 integrated amp. It has a fault.
I'm trying to fix it but don't have the schematics.
Does anyone know where to find one?

Thanks

No, itís standing by, waiting for the schematics. Itís not an easy fault. Changed some components and got a bad sound and some offset. Itís getting dust now.

Hi Ixigen

Sorry, but I intend to keep it. I used to like the way it sounds.
I allready found a faulty "mosfet", although it is not repaired yet.

Sometimes they show on German Ebay, if you are patient enought.

Thanks anyway

Hello,
could anyone give a brief translation of what the russian and japanese guy did with their Musical Fidelity A2?
Just bought one yesterday, and I would like to improve it
Why did the russian remove the opamp, what are the benefits and backdraws?
Why such large capacitors and how are they connected?
You can find the links here:
russian
japanese
Thanks,
Sal

From google translate:

Japanese

http://translate.google.com/translat...tm&sl=ja&tl=en

Russian


http://translate.google.com/translat...tm&sl=ru&tl=en

Still a few mistakes in the translation but good enough to be scary. If it offered design improvements in a couple of years I would not be surprised
