BTW: The transformer needs to not saturate with all that DC current through it. A better way is to let the CCS sink the current in parallel with the transformer and cap, in what's called a "dry transformer" arraingement, so that the transformer isn't getting so much flux for nothing. If the transformer saturates, your return loss will go to hell, levels as well, and distortion rises significantly. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
