Power requirements of 2:90

[ando]

I just picked up a very cheap 2:90 power amp with all new tubes! It's a US model so I will need to use a stepdown transformer here in Australia, I was hoping somebody could tell me how many watts these things use so I can work out whether I need a more powerful stepdown transformer than the one I have. I'm talking about the power consumption, not the power output (just in case somebody decides to tell me that it's 180W because it's 2 x 90!) I'm assuming it will be printed on the back plate of the amp somewhere.

Thanks

Power consumption can't be more (except for some very short time) than the voltage multiplied with the maximum current of the fuse (230V x 4A = 920 W for european models).

When I asked Mesa for my 50/50 power consumption they reply 360W max.
