Dear Amitav,
I have also used Hi-Q International. That idler drive turntable has a lot of childhood memoried attached to it. In 2007 I upgraded to Technics 1200SL:licklips:
In Kolkata you can have a look at:
1. Project Debut Turntables at SKS Traders, Padampukur Near Minto Park
They also stock cartridges, hi-fi speakers. If they don't have something ready request them and they will get it for you from Nova Audio Mumbai (Project Dealer in India). I got my Project Phono Box that way
2. Denon Turntables at ProFX Hindutan Road
3. (Used Turntables) Metro Gali in Dharamtolla, there is a shop which caters to vintage Hi-Fi. But be ready to bargain and carefully check the product
4. For Shure cartridges Dey's Electronics in Chandni Chowk
5. As Murali suggested, it would be best if you get your stuff from HinHuat Singapore. Be it belt/direct drive. It will be cheaper in Sg.
I have PM'd you my number, if need be call me up for further info.
Hope this helps.
Regards,
Prateek
