An Apple MACmini shell gave me a lot reverie, I put it into a small tube amp, there are many photos of the production process for everyone to share.

It is my handmade one of a dozen tube amps. Many other types of tube amps I will go through texture up.
This tube amp with push-pull output power 6W +6 W, toroidal transformer, because my hand is only a 230v-110v voltage, so using a voltage doubler rectifier. Rectifier after voltage 285v.
Noise level 0.02mv, I use 15 inches speakers, sensitivity 97db, still can not hear any noise.
