Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

No, you're not getting it...

"The problem most people have is not with the low DCR power transformers and chokes; these are universally good"

The problem with these designs is that the low DCR chokes have insufficient inductance to properly filter the B+, and the inadequacies of the design are aggravated by the use of undersized filter caps. I've SPICEd these circuits looking back into the supplies, and the source Z is truly awful. They might be passable powering a Class A amp with constant average current draw (and I want to stress that *passable* is not the goal of high-end audio design), but their functionality as a voltage source over audio frequencies is otherwise unacceptable. This is junk engineering in every sense of the phrase.
