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 Kits are designed and put together to enable you to get the best out of your particular amplifier.
The Marshall 9100 EL34 50+50 dual mono block amplifier Classic EL34 Retro Cryo full revalve kit is specially selected for Marshall 9100 50+50 watt valve power amp fitted with EL34 valves. The Classic Marshall kits are designed to give your Marshall the Classic British Rock Tone. This is done by using a combination of classic new old stock and modern day production valves that are traditionally voiced.
The Harma Retro valves really benefit from the sonic improvement that Cryogenic treatment brings to the valves performance. The output distortion is smoother with more detail and clarity under overload conditions. The Rhythm sound is clearer and displays a more transparent quality. Single guitar runs have far more attack and places the notes higher in the mix.
This whole set proves a tighter punchier sound with more attack and better focus when compared to the standard untreated valves.
The Harma ECC81 STR Cryo Balanced
This is a specially balanced valve for use as a driver valve.
The Harma ECC81 STR Cryo is a German manufactured new old stock valve that has been specially chosen for its outstanding performance and sound quality. The Harma ECC81-STR Cryo has a number of important features that set this valve apart from the current production items. The German engineers used the military designed half flange anode plate. This has 3 support rods which run through the anode plate. This design was specified by the military for military contacts as it reduces vibration and shock in critical applications. This valve has a 22mm glass envelope which makes it very resilient to micro phonics and outperforms all modern ECC81-12AT7 in this regard. Sonically the valve has outstanding performance and plenty of gain to dive the output valves.
The Harma ECC83 Retro Cryo Balanced
This is a specially balanced valve for use as a driver valve.
The Harma ECC83 Retro Cryo is a true sounding recreation of the famous Mullard ECC83. This valve replicates the warm detail and harmonically rich midrange that made the Mullard sound so famous.
The ECC83 Retro Cryo retains the classic Marshall crunch and provides a harmonically rich and detailed sound with an excellent 3 dimensional midrange response.
This valve has a traditional British voiced sound and this valve has the outstanding feature that when it is overdriven it provides a warm sustaining sound with plenty of upper harmonics. This combined with its smooth linear midrange response and extended low frequency response means you get smooth warm overdrive with tight fat punchy lows. This captures that classic vintage Marshall sound better than all the other ECC83/12AX7 that I have tried.
The Harma EL34-Retro Cryo is based on the famous Mullard EL34 XF2 design and has a number of important features over standard EL34 types. The grids of the tube use a block construction this enables the valve to provide smoother output and eliminating odd order harmonics. The result is a tight bass response with a balanced sound stage and clean clear treble. Thicker glass not only adds strength but also provides lower microphonics. The valve has a slight midrange forwardness giving the sound a full rounded tone when distorted or overdriven.
The Harma EL34 Retro Cryo will suit the vast majority of guitarists from the classic rock player, the hard rock and metal player who want that classic Marshall sound.
The EL34 Harma Retro Cryo has also attained a 5 star review in Guitar Buyer magazine therefore making this the ideal valve for the governors' amps.
