Orange amplifiers provide the classic Britsh valve amp sound.Since 1968 Orange designs have been very effective as they do not clutter the signal path with gimmicks they simply build amplifiers that are correctly designed and made.

These specially chosen full revalve upgrade kits are designed to help you get the best out of your Orange. We select these valves and supply these in special sets for Orange Owners.
Orange Harma STR E84L full upgrade kit is designed to give you the best clean sound with the maximum headroom and that warm musical chime when driven into overdrive.

The Harma ECC83 STR is used as it has a very well balanced tone with nice even bass. The mid-range is clean and transparent which removes the mush and fizz that happens when the amplifier is overdriven

The Harma E84L is a high quality special application military valve and electrically rated at having a plate dissipation of 14 watts, which is higher than any other EL84, all others being rated at 12 watts.

This is the special burst tested version of the E84L that is tested on the rig built for Brian May for the ultimate reliability.

The valve has a mechanical rugged construction and thick glass as they were originally designed to be immune to shock and vibration as they were designed for military applications

The valve produces the maximum clean headroom out of any current EL84 providing the best clean sound by far in guitar applications. The bass is really deep and solid with excellent balance and no hardness. In guitar applications it offers late breakup and displays a rich warm overdrive sound when distorted which is not matched by any current made EL84. When pushed into distortion the valve produces a rich warm overdrive sound.

The kit consists of 6 valves

2 Specially Selected Harma ECC83 STR
1 Specially Selected & Balanced Harma ECC83 STR
1 Specially Selected Harma ECC81 STR
2 Specially Selected Harma E84L Burst Tested in a matched pair.
