Hi Szaflik,

please see http://www.ub-elektronik.de/download/a100-daten-301.pdf

it is written in german, but you can find a schematic as well as a pcb there, i think. You may buy these pcbs for a small money as well (in germany), the elektor magazine hat an even simpler pcb for sale.

The PDF above talks about TDA7293 (which is newer and some better), but the pcb in it will also work with TDA7294. Feel free to contact the author at info@ub-elektronik.de in english. He is very, very helpful and kind. Ask him about how to put TDA7294 in there and buy those pcbs (less than 20 Euros), which are of good quality and mistakes won't happen ;o)

Apart from this, in Data Sheet of TDA7293 and 7294 there are pcbs.

Cheers
Christian.
