Update: SOLD.
For sale are four pairs of PCBs for the ZD-50 ultralow distortion chipamp. Each 7.5"x2.25" (approx. 57x190mm) 4-layer PCB is for one channel, so you need a pair for a stereo amplifier. The price is $25 per pair plus shipping. PM me if interested.
The design is based on the LM3886 chip amplifier and integrates one channel of the amplifier proper, most of the regulated power supply and a speaker protection circuit on a single PCB. The PCB uses SMT components but is fairly easy to solder by hand, as there are no fine pitch packages.
