Watford Valves has Cryogenically treated some of the more popular and best sounding Tube Amp Doctor 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 has 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.
The TAD 6L6WGC-STR Cryo a specially cryogenically treated version of TAD 6L6WGC STR.

TAD 6L6WGC-STR Cryo is one of my favourite valves as the cryo treatment really takes this valves already excellent performance to another level.

The valve has a ruggedized mechanical construction and thick grade glass which gives very low microphonics. The anode construction follows the classic USA design with that magic black oxide coating. For the record this is by far the best 6L6 type that TAD supplies.

The standard untreated item is an excellent sounding valve, the Cryo treated version is like giving the stock valve a real turbo charged kick.

In our tests the TAD 6L6WGC-STR Cryo produced a number of significant improvements over the standard item. The bass response has more depth and is far more solid with the top end having greater transparency. The valve has better midrange definition and under really heavy distortion provides a rich singing sustain.

The important feature is that it gave greater clarity in the upper midrange with far more presence. This was noticeable of solo guitar parts and power chords as this added a bite to the valves overall sound.
