He has long been interested in music and its reproduction, building amplifiers and speakers for himself as well as for some friends. His current home system includes a home-brew tube preamp, a home-brew single-ended triode power amp (the power in question being all of 2W from a single 2A3 per channel), and modified Klipschorns. This system is seriously loud when required, those sound bursts from Flim and the BB's Tricycle coming across as positively threatening---yet it whispers with a clarity and conviction most minimonitors fall short of. His amp is remarkable in that there is none of the hum that is generally unavoidable with direct-heated triodes. He has designed an indirect heating that relies on very precise balancing of voltages, and has made it work beautifully.
