Ceramic fuses

Personally I think ricevs and George both make claim to more knowledge than they possess.

Steel is a very common component lead material. For rectifier diodes copper clad steel with nickel plate is common.  Even if the lead is plated copper (never bare), the contact is almost always steel or nickel due to bonding issues with glass passivated contacts.   Steel is also predominant for through hole small resistors. Copper is never bare and the solder is now pretty much all tin so the signal passes through a lot of copper nickel and tin interfaces.

Oh there are steels that are not magnetic by the way.

Seems there are certain rules of physics and science that just don't pertain to audio electronics.

You got that right Bill, they think it doesn't exist.
Just too many "snake oilers" and "voodooist" in audio, trying desperately to make big bucks from the gullible with BS, that they can't workout that they are being shafted big time.

All that can be done is to counter the BS they say with hard evidence that there is no voodoo in audio, with EE principals and EE tests and laws.

Cheers George

Repeat after me. "I am absolutely correct. My perspective is absolute and completely free of bias."

People who hear differences cannot be convinced that they don't. People who don't hear differences cannot be convinced that they exist. It doesn't matter how hard you type or how many times you repeat yourself.

Repeat after me, I believe in Shun Mook Discs, Shakti Stones, $150+ fuses and any other voodoo or snake oil that can’t be explained why they can sound better.

Repeat after me: I don’t believe in all laws of electronic engineering, bench tests and measurements.
As they are what’s used to design very piece of quality audio equipment I have.
And if?? the designer listens to it and thinks it can be better, then he goes back and uses once again, all laws of electronic engineering, bench tests and measurements to make adjustments to the circuit and listens once again.

And after all that
Repeat after me and again and again .
"There is no voodoo or snake oil in audio!!!!!!!"

Electrical engineering has no laws, those would be laws of physics but who is keeping track any more
