Default First-timer: advice needed!

I'd like to have a go at putting together my own t-amp using the kits from Arjen Helder.

I've never done an electronics project of any kind (but I'm pretty handy generally and a quick study!).

Can anybody recommend a good book or website to give me tips about how to go about putting one of these into a case. Also where can I source appropriate cases for these units? Finally, what kit am I going to need?

Here are the two products I'm interested in.

NEW tube pre-amp MKIII 12AU7 fully assembled | eBay

New MKIII Tripath TA2020 PCB 25watt Class-T amplifier | eBay

Many thanks in advance - any advice welcomed.

You really just need to understand how to wire it up.

You obviously need a power supply for the pre amp and amplifier.

The only problem you might come across is poor earthing causing hum and this is usually sorted by using a single point ground for all ground lines.
