Congratulations on your new TT, but now you also have a problem in terms of the step down converter which you require to operate your TT with Indian 220V and 50HZ power supply. To solve this problem you need to either change your DC motor so that it works with our Indian power supply otherwise however good a convertor you use it would affect the RPM of your TT due to the 60HZ and 50HZ power cycle issues.
This is the main reason behind unsourcing of TTs from US even if they are cheaper there.

Bro! You're in for trouble.... Like ashish says, you can correct the volatge but there is no converter for the 60hz cycle....
India works in a 50hz cycle. your motor, hence, will not be running at the right speed.....
What Malvai has said is absolutely right but this Audio technica model has DC servo control motor which means accurate speed is governed by voltage feedback. So it wont be a problem. (Just my guess I am not a technical person 
.) Best option is since turntable is already here you can try if someone has a step down transformer.
By the way how much did it cost you ?

Rs. 8800 all inclusive. Bought it from 20north.com, took them 1 month to deliver. Thanx for all your suggestions.... told my technician to unwind the transformer to suit Indian standards.. will keep you posted about it performance once it is on roll!
It would have been better if you had tested it on "Separate" step down transformer with out modifying the original transformer of TT.

I've been through this personally before, with 2 TT purchases in the United States. Just go to your local Chinese Toy store and pick up a el-cheapo 220v-120v converter (usually rated upto 15 watts which is adequate) and you will be up and running. Suggest not to waste your time or money getting this coverted for 220volts. I've used the Teac P988 and Technics SLBD20B turntables (120 volt models) in the past and have not noticed any difference in speed, although pundits told me that they would run marginally slow on a 50 Hz supply. Get yourself an adapter, compate what you hear with a 220volts TT model (perhaps at your friends place) for convincing yourself that there's no noticeable difference, forget the rig and enjoy the music. With this approach, you cannot go wrong.

good move, the adapter should cost you about 100 bucks, all the very best.
I still have the Numark PT01-USB TT bpught from US at which point I was unaware of this cycle conversion issue (I was not a member of HFV 
then). In India its stock power adapter gave up and I got a locally madew 12 V AC 50 Hz supply made by a technician. Frankly like Reuben suggested that I never noticed any problem, except a few old LPs where voice sounded slightly differently which I though might be due to speed correction issues at which I manually adjusted the pitch control of the TT (I guess you should have one too, mine is just like an external volume control)) to adjust the speed in turn and that resolved the problem. 60 - 50 Hz converters are available in India by most companies who build products like Servo Controlled Voltage Stabilizers, UPS, etc but are costlier than normal 220 - 110 V converters.

Honestly, your TT has a DC motor and hence, don't think there will be any noticable impact on pitch. Just sit back and enjoy the music. However, if you must, a simple way to check the speed is to make a paper disk little smaller than your turntable size, put a mark on it and a corresponding mark (a removable one) on your turntable plinth, outside the platter. Set the platter spinning, use a stop watch and check how many revolutions the paper disk makes in a minute. You should have 33 1/3 revolutions for perfect pitch for LPs. My opinion is not to play around with the speed controller inside the TT. Getting the original settings back can be quite a challenge.
In the numark model i have this is just like a externally exposed and easily zeroable once again knob that you can turn or reset (center - zero position does a click effect) as per your liking so was easy for me, not sure how it is handled in the one OP bought.

Hi
I did something REALLY stupid!
I am from India, I recently imported a AT-LP60 USB turntable from USA via ebay. As I connected the turntable on the lines, the trrn table was probably switched on while in transit and the platter rotated once and stopped. Due to high voltage in India my AT-LP60 USB turntable got damaged. I showed it to a technician and he said the Transformer has been damaged (burnt) and needs to be replaced. Do you think there is any way to get this repaired ?
:sad::sad::sad:
[I am talking about the transformer that is connected to the point where the main line enters into the unit.]
