The TELEFUNKEN E88C is the king of the whole ECC88-family. It is among the best audio tube you can possibly get. I have long time experience with ECC-type tubes, espacially the ECC88. The Telefunken E88CC is the best. It is pure GOLD in any audiophile circuit. At Koschuh you can purchase with confidence. Every tube is full working, tested, and in great condition.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 E88CC tubes are tested under the exceptional Telefunken E88CC Data Sheet Conditions:
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.

Offer: Telefunken E88CC Ulm, Germany, (one tube each). Choose one or more tubes from our patch "telefunken_e88CC_180130". They all have the same production code U8015103 (with the ending B or J). These tubes are obviously USED but in good technical condition. More important, some of them have symmetrical triodes, perfect for phase inverters or SRPP. Our storage code: Box number ZH1. I have more E88CC Telefunken from different patches. Please ask. |
Obtained from: military device, well used condition
Test results: (for more infomation: a complete datasheet is included with EVERY SINGLE TUBE)
Tube No.1 = 12.846mA (86%) + 15.501mA (103%) = 80 Euro
Tube No.2 = 12.561mA (84%) + 12.688mA (85%) = 80 Euro
Tube No.3 = 14.323mA (95%) + 14.263mA (95%) = 100 Euro
(tested with ROETEST under E88CC datasheet conditions: 90V anode voltage, -1,2V grid voltage, after 300sec of pre-heat for each triode, whereas 15.000mA = 100%)
Note: Terms apply, see end of this page. Preise/Prices include VAT, if any (*note). Datasheet included with every single tube.
