Ameco AC-1 problem
 

I recently put together the old AC-1 tube transmitter for the 40 m band.
And it works, kind of.

It oscillates nicely but does not have any power.
I know, it is not supposed to have much power but this one is weaker than
weak, the output couldn't drive any antenna.

I was wondering if there are AC-1 owners/builders around here who could
suggest a few things to try, who are knowlegable about this thing.
