In Reply to: Grado RA-1 Battery -to- PSU Mod. Issues posted by Roastaman on January 10, 2016 at 11:51:03:
The 9V batteries are connected in series, so you get +/- 9V (DC). If you got AC adapters, you're out of luck. If you got 9V adapters that have -VE tied to the ground lug of the adapter, then you're also out of luck.
