Thanks for the info, and my apologies to you. I did not know you had designed this amp. I will say I have no experience with it, so I didn't know it had a fan. But, I'm sure you will agree that all other things being equal, reducing ventilation is not a good idea. My only intent was to try to keep the OP from damaging an amp.
Thats cool
I knew it has two fans but better be sure than be sorry
