Thread-topic: 8.97kc - TV transformer info needed
Mike,

it is the fly-back transformer in the HV PS or a TV set.
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.

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
