Default scope horz scale

If you have a scope of 100mhz BW you should be able to see the ringing and most scopes you can expand the horz. I have a old tek 600 analog scope. Also if you go to the URL below he explains this procedure in detail. Happy holidays.

Look for the paper on snubber compensation design. This should help you out . If the transformer is wound carefully you might only have to put a snubber across the primary. Make sure you use a good HiVoltage cap in series with the resistor.

seek and you shall find
