Default F.S: 4 x LM4780 power amplifier modules

Brand new, only assembled and tested modules, as on photos, two with red PCB, two with green.
On red PCB gain and feedback resistors are 0,01% tolerance, suitable for parallel or balanced version.

Price 20 USD per board plus shipping.

Regards

P.S. All four boards are standard 2 x 60 W stereo amplifiers, made with schematics and component values posted on T.I. LM4780 datasheet. The only difference with red boards is that gain/ feedback resistors are 0,01% tolerance, so the both channels are precisely matched which is necessary for parallel operation.
