Description
This Module is intended for replacing the original Topping D01 module of the Topping PA5 amp in case it fails (which it will eventually)
Theres 4 PCB versions that has been tested and are working, select the appropriate one.
Single sided version - recommended, many allready made and in use.
dip8 version - for those who want to use dip8 opamps.
double sided version - not recommended, more expensive to manufacture.
unfinished original placement - parts have the same location and traces as the original, its unfinished and may never be finished since it has the drawbacks of the double sided version
Its recommended to stick to the original parts, OPA1612 and NE5532.
but you allways can go mayhem on what you want to use. weird audiophile overpriced discrete opamps (on the dip8 board or using soic8 to dip8 adaptors.)
