bottom line, any tube power amp with any meaningful power output will have output tubes that will provide a decent amount of heat
flea watt amps still produce heat - 2x 300b’s or 211’s or 845’s or el84s - of course then it is just a matter of degree, one person’s ’minimal and acceptable’ is another’s ’too much’...
hybrid amps might be the answer... really only low level signal tubes produce what most folks would consider insignificant amounts of heat
