I would try to locate old QSTs or Amateur Radio Handbooks that contained such circuits. Tubes such as 6146, 829, etc. were good candidates. Also the 4x/4CX150 would give up to 100+ out with just a few watts in. Newer handbooks or magazines still provide you with he necessary theory to build one from scratch. Building a tube amp is quite simple, just need to have 300 - 1000 volts dc supply based on tube and power out. Also, usually a 6.3vc transformer for filaments. Nothing wrong with tube amps. I have an old Johnson 6n2 unit that runs about 150 watts. Neat old rig. Find an old rig as I mentioned above and go online to the various manual websites and obtain the manual for an old rig. You can use that as your example.
