[Boatanchors] sx-88 manuals and schematics

I'm restoring my Hallicrafters SX-88.  I've got all the data I found on the net,
which is almost "fine". Two problems:

There is no resistance table. Is there one?

While the best schematic I have  (the djvu one from BAMA) is perfectly readable 
for the actual schematic part, the wording is too low resolution to be 
sure of the listed pin assignments, part values, and especially voltages.  

Does anybody have a better schematic and/or a resistance check table?

Oh yes ... I find it amazing that this set ever worked reliably. Wiggling
the 1st RF tube causes intermittent shorts of the plate and filament lugs on the tube socket.
The solder blob on the filament, clearly original, is too big. Easily fixed by bending 
the plate terminal very slightly. (It was straight, now bent, so this was not a post-manufacture problem.)
