  • Notes
  • The company Eric Sundberg was manufacturing radio parts, but only one radio, the crystal set in two versions, with and without longwave. A very nice set of good quality.

    The name ESS intergrades in the name of the crystal set, Hjärter Ess, which is the Swedish expression för "Ace of Hearts". The marks on the detector and the set is a red heart. This version of Hjärter Ess is only for broadcast band up to 700 m. See also the main model Hjärter Ess for up to 2000 m.
