Jerry Electronics TPA3122D2 circuit board with Nichicon Muse power supply & output filter caps mounted on the bottom of the PCB. RCA connectors and speaker wire terminals and Volume pot are all on the circuit board, ala BYOB amp style. Crazy direct signal path! Vintage Simpson DC panel meter on the front indicates power supply voltage. I'm including a AC/DC "wall wart" style power supply, but also recommend using a 12 volt SLA battery for excellent sound. DC input on the back. Power switch on the side. Out of full disclosure, this circuit does exhibit a "snap" sound at power up, but does not harm speakers. I've built & sold many of these. $135 includes ground shipping to anywhere in the lower 48. Also includes paypal fee. Paypal only please.
