Hello,
I'm interested to build this amplifier. It is Geoff's from here:

because of it's characteristics as:
- Pure class A SE
- no CCS, no quasi, just passive load
- can be driven with average preamps
But I want to scale it up to at least about 5W to 8 ohm.
It is good to up 150mW but start to distort at 500mW.

Question:
Is it possible, only with changing component values?
Or circuit must be modified?
Or that 2N3055 just won't go that high?
Thanks
