Toroidal inductors and transformers - Wikipedia

2020-6-15  Toroidal inductors and transformers are inductors and transformers which use magnetic cores with a toroidal (ring or donut) shape. They are passive electronic components, consisting of a circular ring or donut shaped magnetic core of ferromagnetic material such as laminated iron, iron powder, or ferrite, around which wire is wound.. Although in the past, closed-core inductors and

2015-1-20  Re: Toroidal Transformer Winding « Reply #3 on: January 19, 2015, 07:23:33 am » The tubes themselves consume almost no current, but the dynode resistor chain does take some current, depends upon the max signal you expect to see, you can scale back the resistor chain current, but then you get worse linearity at higher light levels.
