Default Help..suggest me a amplifier driver/Motherboard.

Hi friends,
I am a hobbyist from India and I have a passion for experimenting with audio power amplifiers. I Have made several amps from this forum but now I want to make a universal amplifier driver circuit for driving popular o/p bjts like 1943/5200,3055/2955 etc. ,from this forum or others. Since I am not a pro so please help me with complete circuit and pcb.
My requirements are..
1.Fully discrete.
2.TEF driver.
3.adjustable bias & offset.
4.working voltage upto +/- 100VDC.
5.Thermally compensated.
6.Scalable from 50 watt to near 1 KW.
I have searched one fully complete article from the net, please give suggestions about this and if you have something different please share for me and others.
Thanks.
