Unfortunately, this one is also a switching adapter.
So, I’m still on the hunt for a linear adapter for the SBP-1. Apparently, they are harder to find these days.
THIS time I found something for you:
AC-DC Linear Power Supply
Link to 9V center negative linear adapter:
AC-DC Linear Power Supply 9V DC @ 500mA; 2.1 x 5.5mm NEGATIVE center polarity
