JJ Tesla Cryo / ECC83/ECC83S-JJ TESLA CRYO BALANCED
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 is a specially treated cryogenic and selected balanced version of the JJ-TESLA ECC83S.
The Cryo treatment gives better clarity, improved sonics and more detail than a non-treated valve. Balanced with matched triodes for use in phase inverter positions or in high end applications such as studio compressors or audio where balanced halves also known as matched are required.
The JJ ECC83S has become one of the most popular ECC83/12AX7 types made today.
They reproduce fine detail easily and display a warm music sound with excellent dynamics
The Balanced Cryo version is one of the best choices for high end Audio 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.
