• Anotaciones

• Radioset, blocksystem, consisting of four connectable elements.

  In brown oak cabinets with ebonite front, Bakelite knobs and brass coupling strips.

  The set consists of a tuning unit with a fixed and a movable coil, a HF unit with 1 tube and 1 coil, a detector unit with 1 tube and a power amplifier with 2 tubes, probably all bright emitters. The remains of 2 Philips D-II tubes were found inside the unit, so the probable valve line-up was Philips D-II (HF unit), Philips D-I (detector) and 2 x Philips D-II (amplifier). All coils have a solid and a hollow pin. The coils are British, with a pin diameter of 4.8 mm and a center distance of 19 mm. One of the coupling transformers is from the German Böco, and the other is stamped DPM. There are no other marked parts.

  The texts "Erres G RADIOFON" and "R.S. Stokvis & Zonen" are placed on the HF unit. The other cabinets have the text "RADIOFON", with the exception of the last, the power amplifier. An Erres G, made by Dutch firm N.S.F., was introduced in the Netherlands in 1923, but it does not look much like this unit. The only similarity is that it is also an HF module. The link with Dutch trade firm R.S. Stokvis & Zonen (using the brand name Erres) is still not clear.
