MC>Therefore I use some metal film resistors in the
drain/collector/anode circuitry, I choose them so that the quiescent
current plus some tolerance will just not blow the resistors.

This is a good idea. I use it on most of my proto/veroboards too. The
power supply is routed via some 22R resistors... so that if a component
should fail, they tend to blow like little fuses. But better than fuses,
hot resistors give you a olfactory warning too :-)
