Watford Valves has cryogenically treated some of the more popular and best sounding JJ electronic formally known as Tesla valves. This process makes a permanent change and the benefits do not deteriorate over time or upon return to operating temperature, it changes the whole way the vacuum tube performs. The biggest benefits I have found have been a dramatic improvement in dynamic range. Bass response has been clearer with reduction in microphonics. The soundstage is bigger with more detail with a big reduction in the noise floor. The really most starling fact has been how the valve operates under saturated and overdriven conditions in guitar amplifiers. The distortion is smoother with less hardness and is musically pleasing to the ear.
Special Cryo Treated JJ EZ81JJ EZ81 design is based on the original Czech Tesla EZ81 from the mid 1970 period.
The reason for this was that the original Tesla was an excellent rectifier and JJ has followed the original construction to the letter. The JJ is robustly constructed with a thick glass envelope and provides a good replacement for vintage guitar and hi fi amplifiers
The Cryo version of this valve was normally only available in our Cryo full upgrade kits. Due to customer requests we have now made this item available for purchase outside the full upgrade kits.
This is great rectifier valve for the little Vox or any other small audio or guitar amplifiers.
