Accuphase P-20

Part of Accuphase's ver pro-grade looking 1975-1977 trio (quartet) comprising the P-20 power amplifier, the M-60 monoblocks, and the A-version of the C-220 phono pre-amplifier (and, possibly, the mysterious C-22 channel selector that I have only ever seen depicted once in a sales ad).

The P-20 power amplifier is essentially a further development of the E-202/P-250 amplifier circuit, this time in a full dual mono construction.

Curiously the P-20 has a built-in switchable sub-sonic filter. The C-220 phono pre-amplifier, on the other hand, does not, which testifies to the fact that these units were designet to mate.
