The Siemens CCa / E88CC is one of the best tubes Siemens ever built. It is just wonderful. All of my Siemens offers on this page are truly genuine Siemens tube. No fakes. The CCa was a low noise version of the E88CC, sold to the german Post telecommunication service. Internally, there is no difference at all. They were even coming from the same production line. Nevertheless, it could be that the CCa is a factory selected E88CC. For critical circuits. The CCa could have lower noise level and better matched triodes. Anyways, an E88CC with low noise and closely matched triodes could be used as a CCa aswell.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 and E88CC 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 / CCa tubes are tested under the exceptional longlife tube 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.
