If you do take the fusible resistor route, be careful to pay attention to the *type* of
fusible resistor. Some are wirewound; others are composition--the former may well
exhibit a stray inductance that doesn't sit well in a chopper circuit.
Out of curiosity, what does a "fusible resistor" look like? What are the specs?
I hadn't heard of any such thing before today.
In my experience, film resistors (i.e., the conventional carbon or metal film resistors)
are "fusible" -- if you overload them significantly they will release magic
smoke and stop conducting. Is that adequate?
