I bought my MVP second-hand and I think the guy who supplied it just threw in a general-purpose adapter as it doesn't have a Hauppauge label on it. The output is rated as 6.0-7.5V.
Can anyone with an 'off-the-shelf' MVP tell me what the output voltage rating for their MVP adapter is? I wan't to replace the one I have as I think it is the cause of a nasty mains hum when playing music through my hi-fi. I've got a quality 9V adapter which I could try but I don't want to push my luck until I know the offical Hauppauge adapter voltage.
