I'm getting a small pedalboard along the lines of a pedal train nano or palmer pedalbay 50, whatever has the most clearance. I need another power supply as my current one is too tall to put underneath and is in use for my other board.  Anyone have expertise of what will fit underneath?  Only parameters, it has to have 4+ outputs, preferably isolated but not necessary and can fit underneath the board, thanks.  And if it matters I'll be powering low powered pedals, tc electroni
