Elementary Electronics Class D Amp.

[madmike]

Looking for schematic for a simple class D amp project that was published in Elementary Electronics March/April 1975.It used 1-741 op amp,2-555 timers, and 3-bipolar transistors.
Trying to resurrect one of these that I built about 30 yrs ago.If anyone has schematic or scans of original article it would really help me out...
Thanx in advance,
Mad...
