thanks heaps Nino, that is a great resource    very much appreciated.

I noticed that it states the coils on mine to have a diode what will still have to check on the manual but last night noticed no diodes at all on the flipper coils.

Should re-install these.

Another good thing is it shows what williams and bally coils can be substituted for the Sega ones as have a few new bally/WMS ones.
