5 channels rack v4 amplifier from old hub rack

This is my project. I had an old hp hub rack:

and I decided to turn it into a multiroom 5 channels amplifier

This is the empty hub:

I used a led 24v power supply

I created a board with fuses

a lot of modifications to the hub case

and v4 boards

and this is my 5 channels amplifier

tested and works perfectly



A very nice project well photographed and it even works too :slightly_smiling_face:

Great work, I am sure forum users could be inspired by such projects.

Kind Regards, Kevin
