The last couple of days here in Lisbon have been absolutely swelteringly hot - my indoor thermometer is reading 32C at the moment :eek: Outside it's well over 40! I normally leave my amp on all the time but last night as I had some music on I went over to adjust the volume and even the volume knob was hot! The front panel was almost too hot to touch, as was most of the rest of the casing. It didn't seem to be complaining though. It normally gets quite hot near the heatsinks but it's now hotter than its ever been and even when it's just idling seems to be pretty hot. I'm assuming it's just that the ambient temp. is so high that it can't cool down properly. Is it likely to cause any problems? Amp is Arcam FMJ A22 btw. Michael.
