Butler Tube Drive power supply question

photek

I am interested in trying a tube driver. There is a 3 knob version for sale but I can't find any info about how many mA they need to power them. 

This one is a non internal power supply one. I am guessing they need quite a bit of power?

Hi

Hope it's not too late. Got a 3 knob tube driver on the way through a trade and the same question came up.

Not much info around. Only found this. From that I understand it needs a total of 172mA. But I'm totally useless at this so maybe you can jump to a more solid conclusion (or some of the techies can help us).

I'll be trying it out at the weekend (fingers crossed) so I'll give you some more information.
