Die Röhre 300B wird in der Russischen. Föderation gegenwärtig von Electro Harmonix Saratow mit keramischen Sockel und Pressstoffsockel (Typ31) und von Svetlana St. Petersburg nur mit Pressstoffsockel gefertigt. Das zugehörige Datenblatt in rusischer Sprache ist älteren Ursprung, könnte sogar noch aus Kriegszeiten stammen Gruss Hans-Jürgen Heider
