230 Volt don't kill period (just don't mess with it), and it's in a case. The only issue is if it's dangorous to have smps and amp in the same case

Hifimediy T2 with cheap 3A 24V SMPS (brand: JAH)
decoupled with 2200 pF C0G + 10uF Tantalum + 20uF MKP and a Ferrite Bead.


Things on right are mediaplayer, DAC and couple of tomatoes.

Get me a little money for any tombstone proving you wrong, and I will never have to work again.

This ist too serious to play with it. 230V do not kill every time and any one.
You might have survived it. Others will not survive it.

This is what counts: Some will not survive it.

It kills plenty of people in Australia. It tied to attach a Electrical authority document that shows 20 people died playing with there house wiring in one year, but the file was too large, you'll just have to believe me.

Good to see you approve. But the smps is still made with exposed wire as I see it. I have consultet my brother, who have more than 10 years experience in electronic design for the industry. He have a bachelor degree in electronic engineering. He claims my amplifier have no security issues. I don't know your background, but I do trust my brother. I acknowledge that the case is weak, and I will replace that part. He also confirms that in Denmark you don't get killed by 230 volt from you home plug. Only people with a weak hart is in the danger zone.

I think you remarks have been good, because a guy like me should take more care, and not just trust my own assumptions.

This is the amp:

You are wrong. There exist no SMPS at all inside this amp. It is driven by a torroid. All wires are totally isolated. Ground wire is connected. The blue board is not a SMPS. It just carries a rectifier and some caps all working at the same voltage than the amp board.

Please read this safety-warning carefully and please do not tell us no more that 230V is not dangerous.
DIY means fun. DIY does not mean funeral. OK?

Ok. The new build didn't show a picture, so I could only see the one with smps.
Please read what I wrote. I didn't say 230 volt is not dangerous, I clearly wrote that you should take care when dealing with 230 volt, but saying it will kill you is not true. If it was, I would not dare to even replace a light bulb. If you keep on coming with these "it will kill you" warnings - no one will believe you. Just tell the truth, and that is handle 230 volt with care. The electric shock can make you fall of a ladder or might kill you if you are not in a normal healthy shape. Don't scare people, that have never been good tactics, when warning against something.

This is a DIY forum, so precaution and safety always wins no matter who you believe is correct. Please, this is the photo gallery. Any further debate should be split into a different thread.
