- I'm looking for information on applying toroidal inductors in the plate tank circuit of a (large, 4-1000 based) tube HF amp. Are there special considerations in estimating core size and material type

- You need to use powered iron cores. The limitation is the voltage across the windings. On a similar amplifier I used toroids for my 160m extension and split the necessary additional induction into 4

- Hi Dave, Peter, There are many consideration, but saturation is NOT one of them. The tank inductor in a classical tube amplifier sees no DC, and at HF all magnetic materials in existence will melt do
