modify to get negative swing too

 

hi ash,
Welcome to AAC.
Is this a College or Homework assignment?

First, you need to consider what will be required to provide a negative current. Think back to the basic DC circuits class and that will be obvious as to the additional requirement for a negative current.

 

Have a look at half H-bridge and full H-bridge.

H-bridge

 

Change your circuit to "push/pull".

 

It depends on what kind of load you are driving.
If your load is a loudspeaker you can choose one of the following:

1) single supply with capacitive coupling to the load
2) bipolar supply with direct push-pull output
3) bridged output (H-bridge)

 

A pair of key words:
DC bias.

 

modify to get negative swing too

Modify? Don't you mean "redesign"?
The first thing you will need is a negative supply.

You can also add a DC bias and make it a Class A!

For 10A output, you will an enormous heatsink.

Yes, but that meets the requirement

 

AB class direct coupled power amp with + and - power supplies will do the job efficiently.

 

really, THE TS can simply flip that circuit across the "ground" and substitute PNP power transistors for the NPN devices. Then tie the bases of the two input transistors together. Exactly like the very early transistor amplifiers that suffered crossover distortion.
