Greetings to all fellow techs. from Longueuil,Quebec!

Your calculations are right.I think that Luxman rounded up their
power rating to 200W. Looks nicer....

Anyway I would like to learn how to properly adjust the bias level on
any amplifier by using a scope.This would be a very useful tip.

Thanks for the info.

Jacques

Most high power amps I've seen over the years do not have regulated
power supplies and are very sensitive to the AC line voltage. A change
from 110 to 125 volts will cause power capability to go up by 1.29
((125/110)^2). Note that the gain will not change vs supply voltage,
just max level at clipping. How is your line voltage, particularly
under load ?
