More parts I need to replace on the VT100

Having looked at the printset, the first thing that struck me is that 
these are all high power resistors (2 or 3 watt rating). They would 
naturally run hot, therefore, and may look discoloured without there 
being anything wrong with them.

Before we dive into this PSU, I would be interested to know if the thing 
produces any output voltage, and if those 3 resistors test bad on an 
ohmmeter.
