Orange Thunderverb 200 Classic Retro full upgrade kit uses a combination of Harma ECC83 Retro & Harma Retro 6550A to give you the best sound out of your Thunderverb 200.

The kit is designed to give you the classic British Orange sound out of one of the most powerful guitar amps that I have ever heard.

The Harma ECC83 Retro provides a harmonically rich and detailed sound with 3D midrange warmth that produces a huge sustaining tone. The outstanding feature of this valve is it smooth linear midrange response and extended frequency response so you get smooth warm overdrive with tight fat punchy lows.

The Harma 6550A Retro has a rich warm transparent sound with supreme reliability.
The valve has a number of important features .It uses special thick mica with internal bracing and spacing supports with full length anode heat wings to aid cooling capacity and provides improved heat transfer. The plate is constructed out of high temperature laminated alloy with an industrial grade glass envelope to prevent microphoney. The control grid wire is made of gold with a special coated screen grid to improve reliability.

In guitar amplifiers, the combination of these features supply a deep solid bass response with even balance a great high frequency detail. It also ensures that this valve has no harsh or course edges and does not compress when distortion or overdrive is added like some other 6550 on the market.
