From a $48 printed cct. brd. and a bag of parts I fashioned this very functional looking 80W amplifier. The parts include a 6N3 valve (preamp), two TDA7294 high performance power chips and all the parts required to complete the cct. brd. You have to source the rest and that's where the expense starts.
The amp has been constructed in attractive charcoal grey 2U 19" rack enclosure. Three sets of switchable RCAs on the back and 4oz volume knob and Alps pot to control loudness. Speaker protection is included on the PCB and there is a delay complete with flashing led before the amp is ready for use. Very clean sound, holographic presentation.
