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.
This specially treated cryogenic version of the JJ/TESLA ECC83S. The Cryo treatment gives better clarity, improved Sonics and more detail than a non-treated valve. These are the best choice for high end applications and guitar pre amp sections.

The JJ/TESLA ECC83S copies the anode construction of the frame grid design based on the old Telefunken ECC803S. The valve is not a frame grid valve but the valve is very well internally braced which makes it very low in microphonics. The sound of these valves is very warm and clean making these the ideal choice for Fender amplifiers and also for use in audio applications.

The balanced item has matched triode sections for use in critical positions in tube compressors and audio amplifiers. These are matched on dB gain for the ultimate audio performance.
