I'm hoping some of you guy's can help us out with a cheap and very simple design. My ideal design would use as few transistors as possible and give around 80 - 150 watts.
I've been given some lateral fet's and would like to try them out but not sure on power ratings etc. any pcb designs a bonus🙂

Great. Those are good devices.
I can not recall a suitable amplifier.
But for 80 Watt into 8 Ohm, you need like +/-40 VDC power supply.
So you need one transformer like 2x30 VAC. Or more.

You can have a look at this project:
Project 101 - High Power, High Fidelity Lateral MOSFET power amplifier
He even has got a high power alternative.

When you use them -- use them in pairs -- it raises the gm a bit and lowers the THD%
The LM4702 driver chip works nicely with lateral mosfets -- see this application note http://www.ti.com/lit/an/snaa045/snaa045.pdf
