"inexpensive" transformers tend to skimp on the iron, both in cheap iron with higher losses (more heat) and not so much iron (closer to saturation).. You may be working with one that's barely in spec at 60Hz. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
