[Hallicrafters] SX-28 diagrams

[Scott Seickel]

It would be easier to weed through the resistors with a parts
layout, but not a necessity.  I would have figured that there would
be one available considering the popularity of the set.  It is sometimes
hard tracing the wiring because it is bundled.  I have already
replaced about a dozen caps and several of them were the leakiest that
I have ever seen, while others were not all that bad.  I test them all
on a Sencore LC-73 as I remove them just because I like to see how
leaky they are.  So far the resistors are fairly good.  Only had to replace
several.

Thanks,
Scott
