Further to my first posting about DIY sensitive headphones. If you need a higher Z than the 600 ohms of the 'phones themselves, use a Bogen T-725 audio transformer with them to get a Z as high as 40K. They cost about $10 here in Canada. 73, J.B., VE3EAR LowFER Beacon "EAR" 188.830 kHz. QRSS30 EN93dr |
