Voodoo Lab

Hello, I just joined this forum and this is my first post.

2 Technical questions:

1. I'm using two Line 6 receivers, a G50 which is powered with no issue and a G70, which will not power up completely (just one lamp will illuminate, it doesn't power up all the way) Is there a solution for this?
G70 Power Supply image 2. I'm also using a Radial Tonebone that requires 15VDC 400mA. Is there a cable option to power this? I would prefer to not use the courtesy outlet on the back (if possible)

Thanks for any guidance that you can provide.
