Hi
I would suggest that you get your self up on
reading schematics. Resistors rarely just burn
up without there being some other cause. Just
replacing the resistors will most likely result
in more burnt resistors if it is powered up without
locating the reason for the resistors to burn
in the first place.
Many IC's and transistors show little to no visual
indications that they are shorted inside. I don't
know how one can find these without understanding
where the resistors are in the schematic and how
the resistors are being used.

Okay, I pulled the power supply on the VT100 after replacing the two video
board components, only to find 3 resistors on the PSU burned out. I know I
should probably get a book on how to read a schematic (I will soon) but in
the meantime can someone tell me what these resistors are?

I copied a portion of the diagram image on page 23 of the VT100 found at:

If someone could tell me what resistor is what, that would be awesome.
Thanks again for everyone's help (and time)
Julian
