OK,
First things first:
those " square shaped caps with round dots" should not even be touched for testing. Unsoldering them may damage the leads attachment at the potting point. Those are micas, they are presumed good until proven otherwise. All other caps should be replaced.
Now. You never said you tested the voltages.
We need to establish the voltages are present.
Also: do the tubes (all) light up or otherwise it could be established with sufficient degree of certainty that they do (if not visible)? Like measuring at least 7.5V (with the pilot lighting up should be 10V) across the R2, the 50 Ohm section?

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
