hmmm

to the battery, or to the ignition wire should make little difference.

Definietly spark noise, as the buzz does not go away with the alternator disconnected.

thats true. the source of the buzz is coming from the ignition.
how long has it been since you did a tune up?

your original radio didnt buzz but the new one does right?
if so it may be because the new radio is more sensitive than the original, the problem could have just started. but if it were me I would replace all plugs wires I know that although plugs and wires along with dist cap and rotor are wearable items that should be replace as they wearout.

in case you didnt know this but my old work truck is a 81 ford f100 with a 4.9L and it has a condenser mounted on the side of the voltage regulator . like the one in the picture below.
also have you checked that the coil is not jumping fire to the connector. also in the picture below.
