Kit for a pair of mono amps with transformer input : 210RMB ($32)
We are at present only selling amp kits in multiples of two. Kits contain all the parts you need to build 2 off mono amps, excluding power supply. Most of the parts are SMD, the smallest are 0805. If you've only done conventional (through-hole) soldering before this kit could be a handy introduction into surface mount tech. The trickiest part to solder is the TDA8932 itself, it has 32pins on a 1.27mm pitch.
Shipping is in addition and depends on your location and speed of service.
The amp is rated at 25W into an 8ohm load and is BTL - the power rating is a fairly conservative one on music but its not been designed to deliver 25W continuously. The amp IC contains thermal overload protection should its temperature rise too high. The suggested power supply (extra) is a single 24V @3A switching brick for each channel. Thus a stereo setup should have a 24V/6A supply.
