hello,
i would like to know the formula for attenuations of tapped autotransformer, if someone can help me, thanks.

Is that service or what!?
Ok. I put this graphic together after lifting the tapped autotransformer pic from here - http://www.allaboutcircuits.com/vol_2/chpt_9/5.html
This is something I've been meaning to put together for a very long time.
I am indebted to David Smith for supplying the fundamental formulas for my spreadsheet.

Another model using my software showing the spice data
David's LEAP Crossover Shop software is better in that it automagically calculates the secondary inductance value.
Hey,
good stuff Thanks.
Is there some formula to convert it to this series and parallel R/L substituting circuit?
You somewhere posted this for the 3145 network but it would be useful to be able to convert all the other networks with these tapped AT's
Not that I know of. Those conversions were all done the hard way. Greg Timbers supplied the original voltage drives along with a few suggestions and I had to plug and chug until the voltage drives looked identical. I never did get around to doing the 4315, L65, S21, or L220. I think Tim G might be able to import voltage drives into SoundEasy and do something with them.Originally Posted by Guido

Hi Fonzy,
I send you a P.M about this case
