I was told that the 3CX15000B7 would be a good starting point by Eimac.
The heater, grid, and cathode are all the same. The bottom end of
the3CX15000B7, 3CPX5000A7 and YC156 s are mechanically identical too.
The anode of the 15 kW device is naturally bigger than the other two
tubes.. I do have both data sheets, but not handy - give me a day or
two. The problem is I see that the only SSB/linear data on the
3CX15000B7 data sheet results in an anode dissipation a *little* over 5
kW (about 5.5 kW if memory serves me correct), so you cant exactly
follow it, and still stay within the ratings of the YC156.
