These specially chosen Cryo pre amp upgrades kits are designed to give what many Marshall owners have wanted for years, Smooth warm crunch with rich harmonics and detail . We have chosen a valve that which gives as close to the classic Mullard 3d midrange tone and smooth even crunch as is possible. We then select these and supply these in special sets for Marshall Owners. Marshall amplifiers are voice of Rock and Roll past, present and in future.These amplifiers have been used by all the music legends. From Clapton's fierce bluesbreaker solos with John Mayall, to the powerhouse slam of Jimmy Page in Led Zeppelin to Steve Jones awesome sound with his JCM800. These Cryo Kits are designed by using specially selected valves and put together to enable you to get the best out of your particular amplifier. These are the closest approach to the original sound.
This 7-Valve Cryo set is specially selected for Marshall 30th Anniversary Amplifiers and uses a set of Harma ECC83-Retros throughout. It covers all Marshall 30th Anniversary Models that have a 7 valve pre amp section with the phase inverter in the V 7 position.

Our classic kits are designed to give your amplifier that warm detailed valve sound that is normally only attained by using rare and expensive Mullard ECC83.

This has been our most popular Marshall kit for the 30th Anniversary Series. The Harma ECC83-Retro provides the classic Mullard Style 3D transparent mid-range which is warm and smooth when overdriven. The high end is crunchy and clear with plenty of chime. Marshall Owners will also find that this valve has a nice crunchy bite with improved top end frequency response. The bass response is tight and defined giving the classic Marshall tone. The valve is made with a smooth response curve so does not have that annoying fizz when the amp is run into saturation which happens with certain ECC83/12AX7 types. In short what many Marshall Anniversary owners have wanted for years.

The Cryo treatment provides warm clear detailed bass with clear articulation and smooth even distortion when the amplifier is overdriven. The highs have more detail, attack and smoothness which can go from a glassy clean to a creamy sustain.
The Cryo process provides more dynamics than the untreated items and therefore provides a warmth and clarity that before was only attainable by using expensive new old stock valves such as the Mullards.

The Kit consists of 7 valves

6 Specially selected Harma ECC83-Retro Cryo for positions V1 to V6
1 Specially selected and balanced Harma ECC83-Retro Cryo phase splitter for V7
