This is a pair of high power amplifier kits using TDA7294. TDA7294 is renowned for musical and tube-like sound because of the MOSFET output stage. Each amplifier board when standalone is a high power ( 100Wrms@8ohm max, 60Wrms@0.1%THD) amplifier. When two are used together they can form either a stereo set or a BTL mono amplifier up to 180Wrms power . Only a few wires are required to connect two boards together to form the BTL configuration. We do air shipping worldwide at US$5.20.
The assembled board in the last picture of this listing is for reference only. The components in the un-assembled pictures are the actual components to be come with the kit.
