Looking for some info on problem with my DDS

Whats the best way to get more output from a DDS mine only produce 1 Volt @ 50 Ohms and this will not produce enough Grid current in the TX

DDS input into a PCL84 and 12BY7a Oscillator
need to produce around 7 - 10 volts

most people use here also a EF80 or EF184 tube as first stage to amplify the DDS signal before into an EL84.
