Accuphase A-50-Clone

[Blitz]

With all the competence here in the forum I am wondering if we couldn't get a Accuphase A-50 backwards engineered. OK, an A-20 would be good enough as well for my taste. I understood from AMT-Freak that the actualy schematic is not far away from what Accuphase has published in its product information:

Let's collect in this threat sinply all informaion we can find like used transistor types etc. Typically there are quite a bit information available from magazines, people who opened one and made nice pictures etc.

Best Regards

I guess that a view details of the Gigant 2000 can be re-used (even though there are some topics which they have included because they were targetting not for 20 Watt but 2000 Watt)
