If you refer to the many pdf manuals on the web that cover both the BC-224-* and BC-348-*, you'll find they use the same choke (302):  75 turns of #15 AWG wire with inductance of 83 uH and resistance of 0.006 ohm.

>Does anybody know the micro-henry size of the 'RF Chokes' in the 12 volt BC224 dynamotor chassis?  Cogitating on this, wondered if they are based on the number of commutator sections, divided by two considering opposing brushes, that number times RPM to give a possible sparking rate freq which the inductor and capacitor values are calculated on to filter out the racket?  Anyway, needed to know since I am slowly putting together a 12volt dynamotor chassis, and they might even be the same size as the 28volt, but perhaps a bit bigger wire.
