Add to that the blooming. There was no blooming of the picture when the seleniums were in place. Also now, if you look really hard at the video, you can see a very light line going down the center of the screen, which isn't really visible on some stations. Is that horizontal foldover?
So then we're left with the question, is the blooming caused by the low B+, or is the same component causing the blooming and low B+, dragging the chassis voltage down, and sucking current? First thing I'm going to do is test the diodes. Not sure if another diode in series would help matters much, as I got 3 watt diodes. Next thing, I'll re-test the tubes. Beyond that, I just don't know.....

I would first try to measure the current in series with the resistor, to see what the set is drawing off of the B+ line... that should answer the question; "is the set drawing too much current or is the power supply not working correctly?".
