MOD TRANSFORMER TAPS

[W2PFY]

I noticed that on Steve's site for modulation transformer connections, just about all the multi taps types have the secondary impedance written out for us where Thordarson doesn't have that. I guess all they care about is not exceeding the ratings. Maybe there is some other mathematical way to figure this by doing something with the turns ratio?  I know how to figure what the plate impedance should be but its not spelled out for me on their tap connection sheet.

Please remember I am not an engineer so any help is appreciated.

The last column is your key, dont exceed it and then just play with ratios to your favorite RF tubes.

Dont forget as mentioned in the other mod iron thread: That's turns ratio -- full primary to full secondary. Impedance ratio is the square of the turns ratio.
