I presume this is being done to lower the mains voltage, another way is to use a bucking tx: http://sound.westhost.com/articles/buck-xfmr.htm See fig 4. I use one for my KD990 TT as its rated for 220v and our mains hits 250v+ on a regular basis.....

Power(watts) = Amps times volts, so 2 Amps will give you 480 watts - 2 times 240v(mains voltage).
“Music has always been a matter of energy to me, a question of fuel. Sentimental people call it inspiration, but what they really mean is fuel. I have always needed fuel. I am a serious consumer. On some nights I still believe that a car with the gas needle on empty can run about fifty more miles if you have the right music very loud on the radio”

thats over 30 amps. sounds excessive.Originally Posted by walpurgis
I just had a look online. The Krells use 7800 watts max. Quite a bit really.
I just wanted to see if the Variac would be OK with a 4 watt per channel valve amp. I reckon it'll be OK.

“Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".
“You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”
"You don't have free will. You have the appearance of free will.”
“There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”

I have a pair of 2 amp variacs that I used to use for my Ming Da 18w SET monoblocks, which are Class A, so no sudden current draw. One variac would feed both amps quite happily, though. And 240v x 2amps = 480VA. VA is roughly equivalent to watts. In the end I made a couple of bucking transformers for them.
Edit; I should have read ALL the posts before I posted.
