Have a look at http://members.iinet.net.au/~pterren/FlybackTV150W.jpg and= you will see what is meant. Most likely you will have to rewind it. It worked fine here as output transformer in my 136kHz/450W TX but got too= hot in my 502kHz/300W TX. 73, Rik ON7YD - OR7T ________________________________________ Van: owner-rsgb_lf_group@blacksheep.org [owner-rsgb_lf_group@blacksheep.or= g] namens Mike.WE0H [we0h@gmx.com] Verzonden: zaterdag 29 mei 2010 17:03 Aan: rsgb_lf_group@blacksheep.org Onderwerp: LF: 8.97kc - TV transformer info needed Can someone explain what the TV transformer is and a picture so I can find one here? I was doing testing last night with a DDS VFO into a microwave oven power transformer and got the voltage up enough to radiate a 8kc signal. I would like to try a TV transformer if I could figure out what it is and what I need to be digging in my junk box for. Thank you, Mike WE0H
