Default Re: Toroidal Transformer voltage reduction by removing turns

If the secondary is on the outside (wound over the primary) easiest to undo turns. With careful examination, you may find that the secondaries are bifilar wound ( many toroids are).

Mylar tape is recommended after you have the correct voltage, or the voltage you require. At LEAST 3 layers, but 5 layers is better.

For current ratings, multiply the name plate rating by .62 to get the correct output current. Because toroids run such high flux densities, the charging current peaks can be literally HUGE.
