If i'm only going to run one side of this amp (mono) should I tie the other channel directly to ground? ||Thanks

Hello, i did the bypass mod , and i added the volume pot .
There is something wrong , normally when you turn the pot to Zero = no sound and turned Max = max sound, it Dosent controll the volume much, insted i must controll it from My phone ?!

Anyone know of a remote that works with the Lepai LP-2020A+?

Have a look on Amazon eightball i've seen various lapai models there and re-branded lapais with remotes , normally the bluetooth versions. They don't all use 2020 chips though .
Anyone got hold of the new TI 3118 Lapai yet ? ( 2020TI ) .

I think it might be better to avoid confusion to create a new thread for the A+ model of the LP-2020, as the input section is very different from previous versions.

To start with, I reverse engineered the input circuit, and present it here. To follow are the mods I've done so far. In the second photo I have already begun my mods, so don't be alarmed that C20/C21 are empty.

Notice that there is a mistake in the left (lower) channel, C41 is connected to the wrong place. Compare with C40.

Hi,
Will you be able to tell me the values of those capacitors too?
I really would like to know what are the values of following SMD capacitors
C25, C40, C24, C41,C43, C26, C27, C23, C22, C42

Thanks
