Making a choke is quite difficult- why not just use a 100 ohm 20 watt resistor and some bigger capacitors?

If you can't find a choke, it is better for your to build a regulated power supply instead. May be just RCRC filter would be good.

I have heard some of the easy chokes. They also sound like heck

Does anyone know what makes a good sounding PS choke? And why Nickel is so much better?

Well, that sounds like typical listen-what-you-pay-for-ness, Analog.

Hello,
10 henry, 75ma and not for choke-input, just one . Does Vietnam not have army surplus dealers? Maybe i can bring you one when i will travel to Vietnam in december. But there are quite some big differences in sound between chokes. I allways Tango for choke-input but i think if you will not use them for choke-input the differences will be smaller. We will keep in touch. Sincere greetings, Eduard
