hi everybody
I just got some opa 548 and opa549 from TI; I would like to make a small amplifier with these these chips as they seems to be quite good.
As anyone tried this schematic:

else I would like to know what type of power supply to make (size of the transfo, size ofthe capacitors....)
thanks

Look out for figure 3: the + and - opamp inputs are reversed.
