[Amps] Use of toroids in tank circuit of tube amp?

[Peter Voelpel]

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 Teflon isolated T400 cores in series.

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 to avoid
saturation, or other electrical considerations?

Very tks...
