ECC88 & ECC88-compatible tubes: 6DJ8 / 6922 / E88CC / E188CC / 7308 / CCa

Ing. Max Koschuh is specialized in vintage audio tubes. Choose your favorite tubes from the list down below, and let me know. Registered shipping, with tracking number included, in a large and sturdy box. Shipping fee to your country: please ask.

My Tube Tester: I am testing each individual tube on my ROETEST tube tester. This is a computer-based measuring device. Learn more about the ROETEST here.

Satisfaction guaranteed: I want 100% happy customers. Click here for more.

12 months of guarantee: At Koschuh you have up to 12 months of warranty on your tube's purchase. Click here to learn more.

Matching: You can either choose one of our "matched pairs / quads" (if any), or you can "select" tubes on your own, from our list below. You are allowed to mix tubes from different batches. It's your choice. It's your safing aswell. Focus on the criteria that is most important to YOU: i.e. anode current, production codes, balanced systems,.. you name it.

How much anode current SHOULD a new tube have?: Well, there is no clear answer. Datasheet says 15mA, but that's just a figure. From our long term experience, new old stock (NOS) ECC88 tubes - out of the box - could have ANY anode current ("emission") ranging from 10mA to 20mA. Read my complete story on this topic here.

Test Parameters: The ROETEST has fixed test parameters for each type of tube. All of my ECC88 tubes are tested under the exceptional Telefunken E88CC Data Sheet Conditions (longlife version of the ECC88):
Test Procedure: Me and the ROETEST have a fixed test procedure. Read more about it here. And you will also learn a LOT on how to identify an honest tube seller.

Advantages of NOS and USED tubes:
In real life, a used tube COULD sound better than a new one. Also, a used tube could be cheaper. Read the whole story here.

Rechtliches:
Bekannte optische und technische Mängel: Siehe FOTOS und Beschreibung der jeweiligen Röhre/n. Bei englischsprachiger Artikelbeschreibung benutzen Sie bitte den Google Translator, oder fragen Sie die Details nach. Durch Kauf / Bestellung bestätigen Sie jedenfalls, dass Sie die Beschreibung verstanden haben. Bitte sehen Sie sich die Fotos an, sie sind fester Bestandteil der Artikelbeschreibung. Unter Umständen sind mehrere Röhren auf einmal abgebildet, aber der Preis kann gegebenenfalls pro Einzelstück gelten, bitte lesen Sie den jeweiligen Artikeltext sorgfältig durch, oder fragen Sie bei uns nach. Sofern nicht explizit Paarpreise (oder andere Konstellationen) angegeben sind, gilt der Preis pro Stück. Als NOS bezeichnet man eine Röhre die "Neu aus alten Lagerbestand" ist. Als "NOS-like" bezeichnen wir Röhren die technisch weitgehend einer NOS-Röhre entsprechen, aber unter Umständen nicht NOS sind. Falls eine Röhre nicht explizit als neu beworben ist - wobei das bloße Testen mit dem Röhrenprüfgerät unserer Auffassung nach noch keinen „Gebrauch“ im wesentlichen Sinne darstellt - so kann die Röhre gebraucht sein, und ist folglich aus zweiter Hand (in der Regel Militär oder Institute), wobei uns die exakte Anzahl der Vorbesitzer nicht bekannt ist. Röhren sind Verbrauchsmaterial. Grundsätzlich sind Verbrauchsmaterialien von Umtausch und Rückgabe ausgeschlossen, und die Gewährleistung kann gemäß den geltenden Gesetzen und Regelungen für Verbrauchsmaterialien in seiner Dauer verringert oder sogar ganz ausgeschlossen sein. Ansonsten gelten die versprochenen Garantien, wobei als Garantiebeescheinigung die Rechnung gilt, sofern dies rechtlich möglich ist. Die Ware lagert bei Max Koschuh in Österreich. Der Versand innerhalb Österreichs und nach Deutschland ist besonders einfach und preiswert. Selbstabholer sind herzlich willkommen. Für alle Geschäfte mit der Firma Koschuh gelten unsere AGB in der jeweils gültigen Fassung.
