Stupid question department:

AM broadcasters and FM broadcasters generate many kW of power for their 
transmitters. 

Now, naturally, they use much bigger tubes in the final circuits than 
amatuer practice (and regulations!) permits, but what do they use to 
drive the big tubes? Don't they use something like a tube suitable for 
1.5 kW in amatuer service?

Or have these guys gone all solid state for their drivers?
