Hallo! Ich verkaufe hier meinen xDuoo TA-20 Kopfhörerverstärker von Februar 2022 in einem sehr guten gebrauchten Zustand und dazu gibt es ein paar gematchte hochwertige RFT ECC82 12AU7 Röhren. Der xDuoo funktioniert einwandfrei und auch die Röhren wurden nur wenig genutzt. Für weitere Information schaut bitte im Netz nach und auf YouTube gibt es einige Videos zum TA-20 mit Top Bewertungen. Verkaufe den Kopfhörerverstärker nur weil ich zu viele Geräte habe und aufräumen muss Falls es noch weitere Fragen gibt, einfach melden :-) Grüße Benjamin Da die neue EU-RICHTLINIE jetzt 1 Jahr Gewährleistung auch für Privatverkäufe vorsieht - soweit der Verkäufer es nicht ausschließt - erkläre ich, dass ich für meine privat verkauften Artikel keine Gewährleistung im Sinne der EU-Richtlinie übernehme.
