Tda7560 4X50w

What you need for made PCB:

PCB +-70x45mm

Marker or nail polish

Scissors

You can do on pcb with holes.

Water, salt and copper sulphate (you can find DIY stores). Etching is approx. 8 hours if kept warm successful and faster (i use 100ml hot water,4 salt tea spoons, 2 tea spoons).

Salt 60%

Copper sulphate 40%

Be careful with chemicals, after work wash your hands with soap and water.

Clear PCB with aceton and made holes.

Electronic parts:

1x TDA7560 (or TDA7386, TDA7384)

1x 10k ohm (brown, black, orange, gold)

1x 47k ohm (yellow, violet, orange, gold)

1x 47uf

2x 0.1uf (code on caapacitor "104")

2x 1uf (code "105")

3x 0.47uf (code "...474...",)

2x 2200uf can be smaller (It operates without capacitor)

Solder all electronic parts and test.

Maybe next time made new instructables, amplifier TDA7294 bridge 145watt.
