  • Can a Grundig DEM modification be done in my TDA1540 Player
  • Can  i replace the Ceramic or SMD Capacitors by better ones like , C0G, PP ,  PPS,  ect  ect,..  in my CD player, because…..
  • In the Datasheet of the TDA 1540…….

i don’t know the answer, “I don’t drink cognac and I don’t smoke cigars”
