Sorry John but this is misleading. Why, with none valve amps would you ever need signal transformers from pre-amps to power amp stages wrt to audio? Valve amps along with their output transformers introduce second harmonic distortion and are more "classy" in looks than practical as MOSFET amps are far more linear. Transformers in a signal path are for impedance matching. Ideal for RF circuits when other factors are predominant and as these signals are often on a RF "carrier", sub carrier resonances are not an issue, but with audio...reserved for amplifiers with high output impedance commonly associated with output stages of germainium transistors and valves to drive low impedance speakers With modern electronics they have no place. Input amps with KOhms of impedance and MOSFET/silicon transistor output stages with near zero output impedance have no need for transformers. I have never seen a modern amp with signal transformers in their audio path. -- Waldo Pepper ------------------------------------------------------------------------ Waldo Pepper's Profile: http://forums.slimdevices.com/member.php?userid=39029 View this thread: http://forums.slimdevices.com/showthread.php?t=78938 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
