Success!! I have finally been able to get this working. I used the 4700uF cap directly on the breadboard, and cleaned up the circuit after testing all the components. This amp doesn't sound all that great for all the trouble it's caused me, but I am happy to say it works haha.
Now I have some MJ15003 and MJ15004 power transistors waiting for my next project
However I don't feel like frying those, so I'll save that for another day.
I've attached a picture of the circuit below, I'm aware that I'll have to put the heat sinks onto the power transistors; but just lost my patience. Also the diodes should be attached to the power transistors for thermal stability, according to the book.
Thank you for everybody's help and suggestions. @vk6kro thanks for the mod, I will try that tomorrow and see how it sounds, for now I think I'm putting this one to rest though. haha
