I recently checked out a Henry 2002A 2M amp and 2004A 432 amp for a
friend.
Compared to my Commander II the 2004A amps noise (blower noise and
residual hum) is a good 10dB louder. But the 2002A is at least 6-10dB
louder than the 2004A amp. It sounds like more like mechanical resonances
and I hear some droning with the blower. I have tightened up a few loose
screws but overall the noise is still unacceptable.
Has anyone had a similar experience with high residual noise from these
amps? Has anyone had any success in reducing the noise?
Thanks in advance.
