In Reply to: The heat of a headphone OTL amp.... posted by wangmr on August 11, 2014 at 06:19:10:
Put the Bottlehead Crack on your list. It is $280, or $400 with the "Speedball" upgraded p/s. It is a kit, with superb assembly instructions. Tech support, via Bottlehead's forum, with its many serious DIYers who are always willing to help each other, is great. Support from the company via "Doc" Schmalle, is also outstanding. The amp is for high-impedance headphones, and, with the Senn HD800s, produces the best sound I've ever had in my system.I don't know how much heat it puts out, but there are just two tubes; a 6080 and a 12AU7. (Designing an OTL amp for a high-impedance load eliminates the need for many output tubes.) I'm not sure what you mean by vacuum tube heat "getting in the way" of the sound.
