Yeah, I only figured that one dim tube may have been faulty because the other which was the identical type, was a bit brighter. Even when switched, the dim tube remained dim no matter which slot it was in. I don't have a tube-tester yet so it was all guesswork. The bad rectifier was much more obvious, and the first one was causing the transformer to start getting hot as the set warmed up. When I swapped that 6X5 out for another, it ran fine. All the tubes simply glowed orange at the very top, the rectifier and the output tubes were the hottest and brightest but no glowing red plates anywhere. The transformer at this point would only get just slightly warm on top, and I could feel this sort of vibrating quiver coming from it whenever I touched it or turned the knobs on the front of the radio. I've never actually "felt" the current running through one of my radios so I didn't know if that was normal or not.
The weak reception probably was partly my own fault, as I do recall trying to turn at least one of those screws back about a year ago when I first pulled the chassis out for cleaning. I'll have to go back and realign everything once I'm sure it's running like it should be.
Here's a scan of the schematics I acquired, although there is a few minor differences I've noticed. For one, my tone control is the on/off switch rather than the volume knob. The radio had a lot of repair work that I had to sort out which included an added Mallory 2x8uF wired parallel as a 16uF which was used to replace one of the bad 20uF's in the multi-section can. All that's done away with now, of course. I don't much care for the cheap-looking hand-painted resistors, either.
