You can adjust the bias carefully while monitoring the
current through the channel. For this amp you want an
idling heat sink temperature of about 45 deg C (not too hot
for 10 seconds with your hand). The amp takes an hour or
so to drift into the final range, so you have to watch it that
long with the cover on, watching the temp and current draw.
