It's me again... after doing a little bit more research (looking at other 2200 series oscilloscopes with fans) I came to the following conclusions:Those resistors are the load resistors for the output of the CRT
vertical amplifier and they do run hot. They are a common failure
point in the 22xx series oscilloscopes that lack fans. I replaced a
set not too long ago and someone on the list here has also done so
Some of the 22xx series use 3 resistors in series on each side instead
of 2 which distributes the heat load somewhat.
