Hi Bill and welcome,
To add to what Ron said if you have the negative side of 44 connect to the chassis it shorts the bias voltages. One of these is the - voltage found on pin 5 of the 6F6. when it's not there this can in turn causes the 6F6 to draw excessive plate current thus lowering the high voltage. This might be the cause of your fading out issue.
Whatever caps you connected backwards throw them out they permanently damaged (shorted) and are useless. Two things electrolytic caps don't like are ac voltage and reverse polarity.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
