Ignition Miss and Coil Testing

My 86 9000T has an always present ignition miss observed with a timing light
on all cylinders. The symptoms are rough idle and decrease power across the
rev band. The ignition parts are NGK BCP6ES plugs, Bougicord wires, Bosch
cap, rotor and coil, OEM ignition pulse amplifier. I've checked and
rechecked but could not find a specific fault. The plugs, cap and rotor are
15k miles old and look fine. The wires are new. Swap of the ignition
amplifier has no effect. Thus, I think the coil is the culprit even though
its resistances measured fine. Would anyone from San Francisco to San Jose
let me do a test swap?
