Version 4 of PCB based on SMD components is pretty small (20mm x 45mm) and it's very easy to make such installation... But, amplifiers needs +15V and -15V power. So, this external power supply can be assembled from existing parts: 1. Dual Power Rectifier Board Power Board AC 0-30V DC± 0-50V [Amazon](https://a.co/d/8ZW27zU) 2. Liner Power Supply Module [Amazon](https://a.co/d/2BFEFWu) 3. 18V transformers [AnTek](https://www.antekinc.com/an-0118-10va-18v-transformer) Be aware about transformer - the primary coil should match your country electricity specs - 110VA or 220VA. So, selection of transformer is up to you.
