SSE tube amplifier

grabcad

Another tube amplifier, this time not just a 3D model, but the photos of completed unit, above & under the "hood": SSE (Simple Single Ended), using George Anderson's schematic (www.tubelab.com), just made point-to-point technique (instead of using PCB, lost in transit): 5.5 W per channel, from EL34 driven by 12AT7 with CCS, tubes mounted on shock absorbing rubber grommets, large 70 mA double C core OPTs... sounds very nice, just I put in SMPS for filaments (on 100+ dB efficiency horn speakers, there is noticeable hum)...Many thanks to Andrew Whitham for 12AX7 (stand-in for 12AT7), EL34 & octal sockets models
