I think it was called a "cheater" cord because it bypassed the safety interlock. The whole point of disconnecting the AC when the back was opened was that many TV sets were "transformerless" designs, where one side of the chassis was connected directly to the AC line. That meant that running the TV with the back open posed a risk of electrocution, and TV repair shops usually had an isolation transformer for use with cheater cords; it was a 1-1 ratio and served to prevent shocks when the repairman touched the chassis. 73, Bill W1AC ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
