Hi again, True, but the TR7 is all solid state, including the finals. See here:
http://www.wb4hfn.com/DRAKE/DrakeArticles/InsideTheTR7/Inside_The_TR7-01.htm According to that article Drake claims 130-150W output for bands at above 20m and 60-100W on 80-15m. Boy, is that transceiver ever jam-packed! Wonder how it does cooling-wise.
