Siemens are a huge German owned manufacturer that has made and developed some of the worlds best vacuum tubes.
Siemens first patented the x-ray tube On March 24, 1896.
Siemens have made some of the best sounding audio valves that have become highly sought after for their sound and build quality.
Siemens ECC81 is a very high quality ECC81-12AT7 valve which is ideal for all audio and guitar amp applications.These Siemens ECC81 has two important design features which sets it apart from other new old Stock ECC81.
The Germans designed this have with a 22mm glass envelope, this results in very low microphonics due to its thickness. It also uses the military half flanged anode design which was made to withstand stock and vibration.
Unlike other factories like Mullard, the German engineers improved on this design by supporting the internal structure which sees two chrome plates through the side of the valve. This item out performs any modern day ECC81/12AT7 such as the Chinese item and is one on my favourite ECC81.
This valve also has a smooth warm sound so has become our first choice valve for audio application for many years.
It has a rounded midrange which is warm and musical but what sets this valve apart is it is superbly transparent and clear. If your amp is dark then these will give some added sparkle.
This valve also works very well as a reverb driver as it provides extra clarity and lushness to your reverb. It comes in the Original Siemens Orange and Blue Boxes
