Headphone amplifiers / Power supply for QRV07
« on: July 03, 2010, 09:47:23 AM »
I have tracked down most of the QRV07 parts in the USA.
But what about the power supply? How to specify this? Two technical specialists at electronics supply companies said there was not enough detail to select a wall wart. What specs do I need for a USA power supply?
INPUT: 110-120V 60Hz (but how many watts?)
OUTPUT: ???V ???mA
Other???
