Again mfsoa and I have a parallel. The summer temps here in eastern WA can hit 115° F and will hover around 100° F for days on end. I
always have some decent SS gear in-house for just such occasions.
However, my current abode has central air conditioning that seems to be able to handle the heat load well with my Dyna amps. The tube count went up by two outputs so it will be a test as nothing else I own holds a candle to the VAC amps sonically.
