Need help with a Grundig TK248 in Delhi

[blackhorn]

I have a Grundig Reel to Reel Player/Recorder(TK248) which is actually in good working order, but one of its head is not working or is malfunctioning, if there is a restorer/or repairman in Delhi for such vintage gear, or if there is a way I can source spare parts for it, hope esteemed FM's are able to guide me in the right direction.

Thanks you.
