Today I replaced or parallelled (if the deviation was not too large) the resistors.
One particular resistor puzzled me for a while.
It showed 7.3M and it should've been 190K. I 've seen my share of open resistors...but the radio worked fine.
I have another chassis I keep on the bench for reference; it was acquired independently about 2 years ago for $5. In good shape.
So, I looked at the same resistor there, and it showed....10M. I started doubting myself. I even thought it was some variation. I tried to look for 190K resistor but to no avail. Then I measured the voltage on the plate of the IF, where that resistor was the load, and saw 20V instead of 90V.
So I replaced it, and the voltage came back normal. The radio worked the same way as before.
I never saw two resistors in two chassis failed the same way. Bad batch?

Now just replace the electrolytic caps.
