? Dahl transformers have low winding resistance because he uses a high Mu
Hipersil ? core. High-Mu enables him to use a minimal number of turns, which
provides room for using larger diameter wire. For SSB applications, take
Dahl's VA rating and multiply it by c. 3 to arrive at max pep out. For
example, a Dahl 4500VA transformer will produce 14 out with minimal heating.
