I have some notes of one I saw consisting of eleven 4CX250B's which gives a minimum of 200W continuous from 10KHz to 220Mhz, so covers a few bands!

We build these type of amplifiers for use in broadband high power systems used for EMC testing, they work well but harmonics in band are a problem, -15dBc!.
It might be worth looking at some of the Russian GU series valves, cheap to buy and very robust
