Yes. It is a R, C, D network.
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.
I don't have a ESR meter or similar. It is not shorted at least and the
resistance is in the several mega ohm range when measuring in circuit. Are
they likely to go bad in a non catastrophic way?

Peter Coghlan.
