Anything in excess of 5 watts is illegal for cb usage without a permit/license. Frankly if you wanted more than 5 you could just buy a decent cb and run a filter and an amp with a good antenna. The antenna part is important. Many can't support high power loads. They make ones that will support over 50,000 watts that they sell in cb shops and truck stops. The amps and filters are easy to hook up. If you want better power than your average walmart radio a cobra radio with great wires and a real good antenna will make all the difference from a cheap setup. The cost difference is there, though. A high quality setup will run $150 and up, as compared to a beginners setup which will run around $50. High quality wires and antenna are really important. Also, if you really want to run dual antenna's they have to be precisely mounted for distance. The best use for those are with a setup that allows one for reception only and one for transmitting only.

Edit: You're not talking about one of the old 23 band setups are you? As far as schematics I can't help you. Realize, though, there are reasons why vacuum tubes are almost never used. As a mobile setup, there would be issues with vibration.
