[Amps] push pull or parallel ?

[Peter Voelpel]

What do you expect to gain with 3db more power when qsb on 160m is already
much higher?
And you don´t hear anything better when you go qro.
3db more gain with your antenna will be the biggest and probably cheapest
improvement you can get.

Hi,
 
160mtrs contest past and we need more power...  Plan is to add 3 dB by
throwing in another tube  (2.5kw anode dissipation Tetrode, grid driven).
I could go for push-pull of just parallel the tube's. I think push-pull
would be nice to get less even harmonics, but seems to be a big hassle and
just put the tube's in parallel is much easier. Or am I missing something ?
