About 6 years ago, I had got my Telefunken TT repaired at Lekhraj Jasumal on Brigade Road. They used to have a part-time technician come there. He is no longer there now, and LJ themselves have got out of servicing / repair business. Would anyone who had availed of their services know where the technician is nowadays? I vaguely remember he was from Cox Town or Frazer Town (I think -- not sure).
