300W with 24-30v rails? This would only work for a 2 ohm load but would be far beyond the SOA for 2N3055.
I'd say this one is a waste of time, your better off going with the 500 watt amplifier with limiter from apex audio if you really need this kinda power.
plenty on here if you use the search function 😛
You will need more than 2 pairs of transistors per channel (more like 8-10 pairs), and certainly better devices than 2955/3055, to get 300W into 8 ohms... and at least 85V supply rails.
It will need a huge heatsink, and will not be cheap.

That was modified OCL 150W. I post the original here: http://www.diyaudio.com/forums/solid-state/168554-based-hugh-deans-aksa-55-a-14.html#post2225687
hi vedmitraa, why (shaik219) these guy is so lazy to identify the parts from top layout?
he is blind or what?

dear sir,
what is the dimension of this pcb.thanking you,oh yes can u provide me this pcb circuit details thanking u again yours ever masood

This amp use same topology and much more better: http://www.diyaudio.com/forums/solid-state/236138-2sc5200-power-amplifier-7.html#post4262125
