[Hallicrafters] SX-42 out of tolerance resistors

[Julian Bunn]

I'm just starting to look at the electrics of an SX-42. Recently I completed an SX-62 which
is of course almost identical electrically. What I found in the SX-62 was that the vast
majority of the carbon resistors over about 10K nominal value, were *way* too high in
measured resistance. In some cases double, but nearly always 50% higher. I'm finding the
same in the SX-42. For example, the 220K resistors in the audio circuit measure upwards of
350K!

It seems to me that these old Hallicrafters need as least as much attention to replacement
of the resistors as they do replacement of the capacitors. So why is there so much emphasis
on replacing caps ... is it simply because when a cap fails it typically shorts?
