If there transistors had a power supply, then the op-amplifier would not being driving 5Amps through the transistors bases to illuminate the light bulb. As it is the transistors can be thrown away and just use the op Amp to do the work. http://everycircuit.com/circuit/6433338280902656

Check the dots, there is still a lot of current thu the bases.

And supplying power from the op Amp is not a good idea.

what do you recommend changing in the circuit, im lost at this point. BillyT

Here is one suggestion of how it could be done; http://everycircuit.com/circuit/6054281043247104

Try it again, I messed up the first time.

Why use a opamp in differential mode?! Plus if you reduce the the input voltage to say 200 mV then you get a,sin wave out.

Concentrate on each part separately..
