Default Solid state vhf and UHF amplifier designs?

Hi all, Im looking for solid state amplifier designs for use on 144 MHZ SSB of about 100 W output for up to 20 watts drive. Does anyone have links to suitable circuit diagrams?
I am also interested to increase my output power on 432 SSB as well. I currently have 10 w drive and would like to increase that to 100w or there abouts. Solid state amp circuits only please
Thanks for looking
Mike VK3XL

Mike, have a look at:
http://www.qsl.net/yu1aw/VHFPower.htm

A simple design with MRF317 (28V):

You may find some of the transistors used to be obsolete

Thanks Willem, i had already looked at the YU1AW site and have collected a bit of info , but I had not seen the OZ2OE amp design, thanks for your trouble.
By the way I did find another interesting web page with a 2 meter amp design using a MRF245
