Air tight ATM 211 and MAXX

I have currently encountered a shocking and dreadful experience with Air tight ATM 211 mono amps. I did not unplug the amps for 5 or 6 days from AC outlet and after 6 days when I turned on the power amps in a few seconds a very loud and shocking noise appeared in the speakers which I had to rush and turn off the amps before they damage the speakers. The noise was so loud and striking that I thought I had burnt the speakers! What could be the reason and how can I avoid such problem.
Thanks for your advise.

I have run Air Tight ATM3 monos for over 3 years. Always had them plugged in. they have been bullet-proof.

Do you have a tube tester? try checking the driver tubes.

I know Tom Tutay has installed Soft start circuits in many of the Air Tight amps, this could help avoid the sudden rush of current to the amps.
