Zenith 6D029
#7

I've been able to get the recapping finished.  The ecap went back in without too much trouble.  With the smaller modern caps there was more room.  Several of the resistors were also replaced and a 1/2 amp fuse added.

I haven't aligned it yet but it is playing OK (it was playing before I recapped it so I didn't do any damage!).  

I do have a question for Terry or others who actually have an understanding of the way these circuits work.  
Here's a link to the entire schematic.
Below is a cut out of the schematic (left) and then the "as actually wired" (actual wiring in RED on the right)
The 0.0005 uF cap is connected to the plate of the 12SQ7 on one end but the other end is different than the schematic.  The radio is playing.  So do you think this is a schematic error or a mis-wired radio?  Or maybe it doesn't matter??
