Lm3886

Hello all

I have build my first GainClone with the LM3886T
It sounds good and i have no problems but i would like to try two designs more with the LM3886
One is the project of Rod Elliot and the other the schematic of Carlos FM
I try to make the PCB´s for both but i have a doubt

It´s posible to bridge the pins 2 and 4 for continue the V- rail?

Thanks

Miguel

On the LM3886 pins 2,6,11 are not connected internally, so yes you can bridge pins 2 with the -V pin 4.

certainly is thinking outside of the box there...

Thanks a lot

I know thath the question is perhaps a silly question, i dont have electronic´s studies, and for me the reason for build a GainClone is the simplicity, but i have seen that many people dont use this pins except perhaps the pin11 usually bridget with pin4 and I asked me, Why?

Thanks again

Miguel
