And, Japanese equivalents for the A-27 (A-0012), F-28 (F-007), and PLC-590 (XLC-1850), plus a PA-5000 tonearm, all from a 1977 Japanese catalog.

At almost 49 lbs, the M-22 has got to be one if not the heaviest 30 wpc amps out there.

With the recent interest in the A-27 (aka A-0012), I thought this might be worth bumping.
