Zwei Röhrenverstärker Chassis Singel Ended für 2A3 bzw. 300B. nach Loftin & White Prinzip Biete zwei Röhrenverstärker Chassis, wie abgebildet! Der Hersteller der Verstärker ist m. E. Unbekannt ! Es deutet darauf hin, dass es sich um ein italienisches Produkt handelt. Nur ist mir nicht klar ob die Herren Marzio und Jelasi Hersteller sind oder ob es ein damaliges Hobbyprojekt gewesen ist. Fakt ist solche ferigen Triodenendstufen werden heute noch für einige Tausend Euro angeboten. Die Gehäuse sind in einem, dem alter guten entsprechenden Zustand. Mit etwas Pflege und Mühe können daraus wieder zwei wunderschöne Endstufen entstehen. Die Gehäuse wurden vermutlich in Handarbeitgefertigt, bitte erwarten Sie keine Neuware oder ähnliches. Die Holzzarge ist in einem ausgesprochen ansprechenden Zustand.

ON PARLE SUR INTERNET : «FORCE : Purement musical, clair, naturel, je ne peux pas penser à une meilleure performance - ce sont des amplis exceptionnels (avec les haut-parleurs à haute efficacité appropriés). FAIBLESSE : Aucune (sauf dépendance à lefficacité des haut-parleurs)» AUDIOREVIEW.COM «Que puis-je dire. Ils doivent être quelque chose de très spécial (et croyez-moi, ils le sont). À mon avis, ce sont lun des amplis SE Triode les plus sous-estimés. Je dois admettre que jadore le son des tubes 2A3 et, pour moi, ils sont plus musicaux et justes que les tubes de sortie 300B très appréciés (cest peut-être une question de goût personnel, bien que le manque de haut-parleurs à haute efficacité sur le marché rende plus facile à comprendre pourquoi lindustrie se concentre sur les 300B plus puissants).» Si le prix de vente dépasse 1500 euro, je rajoute les deux câbles d’alimentation 3x6mm2, C-004 et P-004E (Beryllium Copper) présentés dans les dernières photos (ils ne font pas partie de la vente).
