Elso, I just noticed I might make confusion. The drawing I referred to (in my posts #19 and #22) is in your post #12, not #13.

Those of you who have tried four parallel TDA1543 chips, have you soldered them on top of each other or kept them separate, each with their own decoupling cap?

I've soldered 2, 3 and 4 on top of each other.. seems to work OK, but they get very... very hot.. better use 5V supply and not the 8 or 9 volt you can sometimes see in a schematic..

Goodluck,
Thijs
