Well I live in the SanFernando Valley of LA. It do get hot here in Chatsworth; no doubt about it. I ran CJ monos for years. Those be the Premiere 5's and 8's (28 tubes) I also had two dif. 845 SET monos and I never worried about my toaster going on the fritz.
I now have the CJ 350 ss. Mine runs cool to warm depending on how hard you push it.I can also say it is just a better amp than the 5/8's. I also had the Belles 350a ref. and it runs as cool as the CJ 350ss. Neither of these amps ever had me wanting me to go back to tubes. The cost of operation is soooo much nicer,too,w/ no tubes to replace.
