Component layout:
The connections:
Mains switch, Power connector, 2 speaker connectors, RCA connector
Volume knob:
The power transformers.
The left transformer provides 200VAC. The right transformer provides 15VAC glow voltage.

I have had a bearing holder for my Z-axis made (I cant drill such large holes here at home):
Thanks Jaak!
I went to a metal store to buy a piece of aluminum bar (30*10*2000mm). I used this bar to attach the Z-axis to the X-axis. Therefore I also gotten a aluminum plate.
I’m also thinking how I’m going to build the X-axis. I think it is best that I make a metal frame with the guide rails mounted to it. Here is a drawing of what the frame is going to look like:

Today me and my dad made a part of the X-axis construction from steel square pipe.
Better pictures will follow when I get the bearings ready.
I made some drawings of a table where the cnc will be on.

The amplifier is almost finished, but testing points out that I have a nasty 50Hz buzz on the output.

I bought 4 inductive sensors from Omron for cheap.
Thanks to Peter.

I’m building a 5.1 surround sound system. Therefore I need a subwoofer. This project is the amp for that subwoofer.
The circuit drawings that I want to use for this project can found here:

Today I mounted the heatsink on the enclosure:
