I recently acquired an su-v3. I removed some customization and did a bit of repair; http://audiokarma.org/forums/index.php?threads/technics-su-v3.746425/ and now in service. Its a modest unit but has no trouble putting out clean power. The small form factor is welcome- and the thorough service manual is even more so. The beancounters were clearly at work in these designs but they sure are easier to work on than the usual rats nest harness from 70's vintage equipment.
