The PS-15 is a new GlassWare power supply kit for tube fanciers. The PS-15 fills a gap: a power supply for those who need a high-voltage power supply with two sets of regulated low-voltage power supplies (usually for powering heaters).
Each PCB holds two cathode-coupled line-stage amplifiers; thus, one board is all that is needed for stereo unbalanced use (or one board for one channel of balanced amplification). The Cathode-Coupled PCB makes building a standard-setting line stage amplifier a breeze. This assembled board with a chassis, volume control, selector switch, power transformer, and a fistful of RCA jacks is all that is needed.
