R27 is part of the snubber network on the primary side of this forward-type
SMPS PSU. But why it it getting so hot. Is it normal? I have completely
forgotten how a VT100 smell when running...
Snubber as in a resistor in series with a capacitor across the primary?
If so check the capacitor for leakage (electrical, not liquid) or being shorted.
