The manual is correct -- the HEADPHONE output is isolated with resistors. The SPEAKER output is NOT, and putting a two-circuit plug (mono plug) into it can cause the output chip to fail destructively. Again, the SCHEMATICS are on line. Study them. We're hams. We passed exams showing that we know this stuff. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
