@Pavan - Do not go for the servo stab. You might want to refer to my post. I got one and it went bust. Get the 1kva voltage coverter instead. It's nothing but a straight forward torroidal transformer inside a box. Get a decent 230v servo stabilizer from say Krykard or Vertex (I've got a 3Kva Krykard Servo and it's a real useful equipment) and plug this 110v converter into it. That would keep your AV electronics stuff singing for years without a problem.
Edit: OK, I don't understand what he means by voltage converter and also don't understand how it can have a varying input voltage range of 170v - 260v and still output 110v? What I meant in my post above (and what I have) is a straight forward step down transformer. Feed in 220v it will output half of it. I feed it 230v (output from the krykard) and it outputs 115v (measured it with a Fluke multimeter!). The US sourced electronics are anyway all 120v rated.
Now ask him for a 1kva step down transformer. I got mine for the same cost he's mentioned (2350)
I think voltage converter is same as transformer, isn't it ? I thought the Maxine built-in stab is servo based, at least thats what the Maxine's response claims. That's why I asked Venkatcr for his commemts because I read on other thread where Venkatcr mentioned that the Maxine stab is not servo based.
I actually asked Maxine about the noise of the stab to which they replied that since there is a small motor inside, there will be some noise when voltage is adjusted.
