Hallo, ich biete wegen Umstellung auf Mono Blcke einen sehr guten Stereo Rhrenverstrker zum Kauf an. Der optische und der technische Zustand sind sehr gut, fast neuwertig, hchstens 20 Betriebsstunden absolviert. Guter Klang ohne brummen oder knacken. Hersteller Garantie bis Ende Januar 2025. Keine Rcknahme, keine Garantie.

Hallo Ich verkaufe hier eine Rhren- Endstufe der Marke Nobsound. Das Gert ist sehr minimalistisch. Die Endstufe ist fast neuwertig. Sie hat nur 20 bis 30 Stunden gelaufen. Manche schreiben zweimal 26 Watt dazu, manche zweimal 35 Watt. Ein versierter User meint,durch die EL34 mssten es 12 Watt pro Kanal sein. Getrennte Ausgnge fr 4 und 8 Ohm. Durch Class A hat sie ein sehr sauberen kristallklaren und satten Klang. Ich glaube sowas ist nahezu Unverwstbar. Kenner wissen das zu schtzen. Die Mae sind ca.: 36*26*18cm. Privatverkauf Keine Garantie/Gewhrleistung. Keine Rckgabe
