  Ortophon catalogue 1975, page 8, meldet "Die Hi-Fi-Druckkammer-Einbau-kombination G3037 nennen wir, allerdings zu Recht, ein "Evergreen", denn seit nahezu zwei Jahrzehnten führen wir diesen Typ, ..."

  Im Laufe der langen Produktionszeit wurden die Chassis mehrfach verändert, so erhielt z.B. der Basslautsprecher eine dickere Membrane, was seine Membranresonanzen und seinen Kennschalldruck etwas verringert hat.

  G3037 was delivered with speakers and optional transformer to produce multitude of speaker impedance values, clearly targeting use with tube amplifiers. Delivered with drawings for enclosure, to be procured separately.
