How about heat sink temperature rise with normal use?
I personally feel the heatsink is too small for 2 Lm3886s, unless you put a small cooling fan.

the heatsink install on the aluminium chassis.the temperature is usually around 40 degree.I can touch the sink.

P.S.
The power supply is 2*18VAC.the loudspeaker is 6 ohm.
