Now the 30w module is tested and i found a reason why heatsinks are not mentioned anywhere for these amp's
they aren't needed !
i had a 18v - 2A power supply and a old mp3 player as signalsource and fed my bookshelf speaker (40w - 8 ohm) and
had volume set at around 90% and after 30 minutes i measured 38 degree celsius on top of TPA3110 chip and that was
without any heatsink i just mounted 4 pcs of 8mm brass spacers to pcb for mounting inside speaker .
That's not bad at all , power supply got little bit warmer thou at 43 C so i try with 22v - 3A and see what's happening.
When time comes to put this little module inside the speaker i will go for the 60w version instead for the 30w.
