Group, Can I use a BC-348Q dynamotor (seperate from the filter box mount) for a BC-348-S? I have the filter mount & intend to wire the dyno to the mount (I had to re-build the filter mount) I noticed there is a little bit if 'back' bias on the 348-S (approx -17 Volts) Brad Send instant messages to your online friends http://au.messenger.yahoo.com
