Default LM3876 GC without any capacitors

At first it was for fun, build LM3876 amp without any capacitor
With battery power, it's easier to remove capacitors of a basic schematic..
I used what I had on hand, pcb from Chipamp, and battery from an electric drill..
And it's works, better than I expected..
At this time (one hour of listening), only bass is a little less "strong" than LM1875 with capacitors, but mid is amazing, detailled, natural..




PS : speakers are 4 Ohm

It's works better today
Nice sound, amazing details !
With LM3876 pin 5 is not connected, with LM3886 it's connected to pin 1 (V+). Using chipamp pcb for LM3886, I did not pay attention to that, new pin 5 problem ?
But I don't knaw why pin 5 is NC for 3876 ?

Interesting choice of wires for signal and signal return from RCA's to board.
