Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

hello, could anybody tell me how to figure out the primary input pin(with approximate 1ohm coil inductance? how to find the polarity for 2 input pins as well..)and the secondary high voltage and ground pin for flyback transformer.. thanks

I assume you mean flyback transformer as used in a TV or computer monitor, not the kind of transformer used for (relatively) low-power switching power supplies. If I'm wrong, please correct!
There are several varieties of flyback transformer on the market. One kind has a terminal common to the primary and secondary, the other does not.
Often, the output is a separate socket or lead, with high voltage insulation - but not always.
To muddy the waters even further, many modern flybacks are actually integrated power supplies - commonly a voltage doubler or tripler is built in to the flyback itself.
So you need to be a bit more specific about what you need to know, and where you're starting from!
