Sam:
Better or worse is a judgement call. The ’58 Seventeener II portable version was prone to fire risk from routing the yoke wires around the filament dropping resistor, an underrated B+ shunt resistor, IRC sync diode and sound buzz.
The ’59 version fixed most of the bugs. A tube, 2EN5 or 9BR7, replaced the phase diode, improved IF can for sound, higher wattage resistors, etc.. It was then jammed into a tighter space so it runs hotter. The long CRT leads make for touchy sync if not dressed properly. The chassis was also used for the low end, conventional 21” models.
The ’60 version was a much better, all new design using a power transformer and improved tube line up. The ’58 series string chassis was dropped all together. (It may have been used for a few 1/2 year carry overs or motel specials, but certainly gone by Jan, 1960.)
I do not have Sams literature. I use Philco or Beitman’s, which is a copy of the Philco. I find Sams makes some errors when redrawing the schematics. Can you see a chassis and run number? It should be something like 9H35/9H38 and run number 121, 122 etc...
The tube line up should be the same for all ’59 versions. The only variables I remember are some tube numbers (locations and functions remained the same) and a optional UHF tube and CRT number. Any schematic for that chassis number should be OK. Late engineering modifications and service bulletins may show up in the TV since they were incorporated after the manuals were printed. Documentation may be in the batch of Service Bulletins that followed the product release.
