    I'm a diy fan and longtime builder of diy musical fidelity A1 A100 A1000 and so forth. I got the copy of the A1 circuit in 1991 from the Dutch importer of MF stuff (but had to keep it secret!). It was Mr Hennessy who for the first time wrote publicly about the A1 and revealed its schematics from own research! Since that time I recommended this site to many friends for advice and explanation.

    (BTW still puzzled about the claim of TdP about the 20Watt class A claim of A1 with only 700mA standing current, but in the end he IS the designer, so ....)
