Never seen one of these before but it's a Small amp manufactured by PS Audio.

I believe the model is SPR-A1

Known as the Sprout.

Apart from that i literally cannot find any other info on this thing.

compare signals for each channel and see where it stops .. you will need data sheets for the ic.s first .

R333 (3R9) O/C

Suspect it has been taken out by IC302 which i need help to identify.

It's marked Abletec.com C1 & below that is 306P

Swap the good IC where the bad IC was, fix the resistor and see what happens.

Edit: plenty of abletec.com C1 on AliExpress.

Hi,don't want to cause more damage as components around the suspected faulty chip blown.

Ordered a chip from Ali , but not sure if the 306P marking has any significance , or is some sort of batch code.
