Thank you for your response. I did have a look for another power brick, but found the 4.16A ones a little difficult to locate.
I have since acquired another MTV 3600 from Trademe, and this came with a 12V 2A (presume after-market) power adapter. I've plugged it into mine and it's away. The adapter after 30 minutes of running is barely warm.
Anyone care to comment if this unit will be good enough to run the MTV long term or should I hunt down another more powerful power brick?
I've asked the seller how they acquired the power adapter too - incase they can shed some light on it.
Their unit was an MTV-3600 with a small fan at the back (presume earlier version of the same unit - looks identical on the inside other than the fan).
The one I have doesn't have a fan, just some vents at the back. Can't say mine ever got warm enough to need a fan.
Thanks.
