Power supply inductors (what specs?)

[Salas]

Hello again

Analog_sa

Mine are custom made by a local toroid firm in Athens. He cuts the core and puts a spacer. He uses italian toroid cores.
In preamps I use non gapped.
In page 2 of this thread there is a post about that and a url.

Try em out, listen you will see (not with B&Ws )
On the other hand if you dont find any differences in your system thats ok. spend on components that give you best bang for the buck. But experiment! thats the magic of DIY.

I will diminish now and go to the west...

[Bertie]

B & Ws??? you lost me.

I don't have B&W speakers myself, forgive me if this is not what you mean or if I've missed something.

Listen & you will see is a marketing motto. Diminishing to the West is Tolkien (excuse my obscure humor).
Yes your estimation about the aircore should work.
Visit Musical fidelity site also. They champion a major cause for pi filters there.

Thanx

For analog_sa

Wanna try out something special and not so terribly expensive?

Beautyful sound and finish for your tubes. Chokes with magical balance. OPTs, ITs, and plate chokes too.

Happy tweaking

Nick

He even suggested that they make 12ga wire in a square form, and would help eliminate the air gaps in the windings.

Does anyone have any clue about the best design for power supply inductors?

What is a good tool to figure out how much inductance to put in a power supply?

How many watts?

Nelson has described howto make good air-core inductors
for supply filtering in some of his amplifiers.

Such excellent inductors can be very, very large !!!
But nevertheless they are very goooood !!!!

Here is one that is the size of a FOOTBALL ( soccer ball )




Enjoy

I can supply 12 gauge 2mH air cores if needed.

Hi Lineup,
what weight of wire is in that air core inductor?
