Hi Ron,
I know I mentioned these to you in another thread but I tell you honestly you have never felt heat from amps like amps with a bunch of 6c33C tubes!
I had the very excellent sound Silvaweld OTL reference monoblocks many years ago and they had "only"4 x 6C33Cs per channel. I had to get rid of them because after a couple hours of running they had my room a good 10 degrees hotter! I was having to listen in my underwear!
The Rites of Passage will put out heat like you never thought possible from an amplifier. I doubt the VTLs even come close despite the much higher power rating. It is not even that the Rites will run so much lower bias it is the damn heater on these tubes that draws a few amps...per tube. I have never felt a tube run so hot before or since.
Recently, I had a pair of Wall Audio M50 monoblocks that have 2 x 6C33C per channel as PSET making about 35 watts per mono. They also ran ruinously hot. Now the Ayon Crossfire, which makes almost the same power but runs much cooler because the heater filaments don't draw this ridiculous amount of power.
Not saying you shouldn't check them out but I am saying that you have not been prepared for that kind of heat before. It will be dissipation of over 1000 watts per monoblock.
I love this post...Morricab,you nailed it with regards to the heat problem.
Listening in one’s underwear,lmao...
At least Ron cannot say he wasn’t warned...
