Really nice work there Trampe,good project that I could really use.the smaller pcb your talking about is it going to be mostly surface mount or through the hole?

All IC vil be DIL (through the hole) and also every capasitors (except 100nF).
 Resistors will be 1206 (SMD) If you have problem to get the TDA8444 (DAC) then try Cricklewood Electronics Ltd  (sales@cricklewoodelectronics.com ) costs £2.50
