** The LM 324 can deliver and sink plenty of current ( 10mA or more)
when operated from a single supply as long as the output swings not closer
than one volt to the supply or ground. Things are not so good if you AC
couple the load.
I expect a pair of AC127 /128 connected as followers work very
nicely as they are direct coupled to the IC and likely bias themselves due
to leakage current.
