2x5W Amplifier for mp3 player or line output (MK190)

2x5W Amplifier 
for mp3 player or line output

To continue the project of making an Audio Amplifier for my devices (as written when recycling an old power supply), here is the nearly step-by-step WIP : 

The kit used is the Velleman MK190 2x5W.

Perfectly noob-friendly protocol:

Steps 1-3: 

Step 4:

Step 5: 

Steps 6-10: (forgot to take pictures..)

Step 11:

Does it work? actually, it does!

The set up: 

• Old Speakers taken from Out-of-Order HiFi, 
• My lovely Old Robyn (Xperia X10mini), 
• Old VHS power supply,
• Spare cables taken from trash electronics (burnt ATX-PSU),
• A little jack-jack 3.5 cable (1.50€)
• Velleman MK190 kit (9.90€)

So i simply used the old power supply to get 12Volts : 

Plugged pin 5-6 (12.6V) and 7-10 (ground) to the power input of the module in a quick and un-recommended way : 

Now that it works, what's next?
The only work left is to make clean and safe connections to the power supply, and find a box that fits all. ==> Making safe connectors

Part 2: A better looking result
Part 3: Adding a better PSU
