Bypass Sprout 100 power supply?

Hi Paul and co-

I had the opportunity to visit your company in the fall and really enjoyed seeing where everything was made and listening to the reference system. I had to balance being polite and wanting to listen for hours.

As a very satisfied owner of a Sprout 100 and as an electrical engineer, I was looking into bypassing the internal power supply and providing DC power from an external supply.
It doesn’t seem to be as simple as unplugging it and applying ~35V to P105. The power switch doesn’t work in that case.

I realize this would be voiding the warranty, but that’s part of the fun.

Any help would be appreciated if this is something you/someone would consider helping with-

Thanks!
Andy
