I extracted some of this information from the old Topica Loopframe_Guzzi news group (which has now moved to Groups.io). The epoxy-filled Bosch Blue
is the most frequently cited alternative coil used (some report bad experiences with oil filled coils). Whichever one you choose, be sure that it has 3 Ohm resistance. A great cross-reference is any Volkswagen Beetle manufactured between 1975 and 1979 (12 volt).

I have been using this one on my Ambassador for several thousand miles and it has performed quite well. I chose it because it was cheap and readily available at my local store. - Bosch Blue ZX075527P - JC Whitney
