Power adapter to use with Suhr Koko Boost and ISO pedals

[Econ]

Hi:

What kind of power adapter would you recommend to use with the Suhr Koko Boost and ISO pedals?

Thanks in advance for your feedback.

Current consumption is 8ma so anything higher than that, boss supplies are fine
Stay away from switching supplies and only use linear supplies
Power Connector: 9Vdc, center negative, 2.1mm x 5.5mm
Operating Voltage: 4V to 18V (nominal 9V)

Thank you Mr. Suhr!
