Okay, this Transitone is killing me....

I replace some resistors that were out of spec, and the picture is better.
But, I think what's going on mostly is there is a loud buzz or hum, I can't tell, and it is only present when you turn up the volume. I think the noise is interfering with the picture.
I checked all the tubes for shorts, they are fine.

The two largest electrolytic caps were valued at 200uf each... I used 220's. Would that be okay?
Also, I put two caps together to make a 40uf, I used a Sprague and a Illinois together, that wouldn't matter would it, using different brands? Both were pretty close to the same voltage.
Just wondering where that loud noise is coming from in the volume?
