Then the reason you have no RF power is that you don't have high voltage on the tubes.
You should hear some activity from the transformer, a buzz, growl or tone.
If not, you probably need a set of six of those doorknob transistors.
Or, more correctly two matched sets of three.
Maybe. Other things can shut down the high voltage.
But blown power transistors was the most-common cause back when we were still willing to fix these.
A long time ago.

What voltage should i get out from the transformer
