I just upgraded from a Jolida JD302CRC (50 Watts) I used EL34,and KTT7 power tubes (matched quartet) and in my normal sized living room it was not a problem. Watchful with pets and children as it was open chassis with pretty tubes glowing.
My new amp a Jolida 1000 BRC (100 watts or 150 watts with 6550 tubes) It has 8 power tubes EL34’s so far, and it puts out a tremendous amount of heat. I live in Fresno, CA the last day day it was not in triple digits was a month ago and I am using a cooling fan on it. It has tubes covered behind glass and surface temp was 143F, with fan about 101F. I have it in a salamander archetype rack I hope it don’t bake the component above it. My last Jolida has lasted 12 years with only tube changes, and pot cleanings. Simple-Perfection. My Preamp is a Cambridge 851N [network streamer/preamp/dac]. I run Amp in bypass mode for all but vinyl for that I use Vincent PHO 8 phono amp VPI Scout Jr. Grado Platinum Reference MM.
