The Golden Dragon 811 is a glass power triode, high-mu, and is mainly used in older transmitters and equipment. Manufactured in China to strict UK specification.
GD EL34 Premium
The Golden Dragon EL34 is a power pentode tube manufactured to the highest standards resulting in superior performance and reliability. This is a most popular tube with guitarists and audiophiles alike. The Golden Dragon EL34 is manufactured by JSC Svetlana, St. Petersburg, Russia, before testing and matching at the PM Valve Labs in the UK.
GD EL34 / 6CA7
The Golden Dragon EL34/6CA7 is a recent addition to the Golden Dragon range.This is a quality robust tube which has been successfully used by guitar amplifier OEM for some years. This tube is the perfect choice for a balance between quality and cost. Made in China.
This is an extremely popular miniature 9-pin (B9A) power output pentode designed for low to medium output audio power amplifiers. Push-pull, ultra linear (class AB1) can be up to 17w. Also often used for single-ended class A operation in small low power amplifiers of a few watts. maximum rated anode dissipation is 12w.
GD KT66 Retro
The Golden Dragon KT66 Retro combines the same shape and style of the original GEC and M-O valve designs with modern materials and manufacturing techniques. These audio tubes are of unsurpassed quality and reliability. Manufactured using the finest materials, these tubes not only look the part in vintage and modern amplifiers but will perform at least as well (if not better) than the original designs from GEC or M-O in all important areas, and can be expected to last at least as long as the originals. The tubes measured electrical performance matches the original GEC and M-O data exactly, and are branded in the style of the originals.
GD KT88 Retro
The Golden Dragon KT88 Retro is produced to a similar shape to the original GEC/MO design, and has identical operating characteristics. The GECKT88 was a higher power version of the original KT66. Developed in the heyday of push-pull working its relatively high output makes it ideal for driving difficult loads of current-hungry speakers. Although it can be used in single-ended circuitry, its more common usage is as a push-pull pair where its low screen current properties give it high power efficiency. The Golden Dragon KT88 Retro sets the standard for others to meet . Its range of applications is wide and it is commonly found to sound superior to other KT88s at a highly competitive price.
The Preamp Tubes...
GD E81CC / 12AT7
The Golden Dragon 12AT7 is a very popular preamp tube, offering a rich crisp sound quality and low levels of microphony. It has a classic mid band sound with ultra low noise and distortion. (AKA ECC81) Made in China to strict UK specification.
GD E82CC / 12AU7
The Golden Dragon 12AU7 is another popular preamp tube offering slightly more output than the 12AT7 whilst still retaining low levels of microphony and as a result is commonly used as the phase inverter in higher power amps to achieve a cleaner sound. (AKA ECC82) Made in China to strict UK specification.
GD E83CC / 12AX7
The Golden Dragon 12AX7 is one of the cleanest and purest sounding 12AX7s available today. Its low noise characteristics and reputation for good quality make it the ideal choice for audiophiles. (AKA ECC83) Made in China to strict UK specification.
GD E83CCT / 12AX7 'Trustworthy'
New generation ECC83 tube, manufactured using traditional British 'Trustworthy' standards giving solid construction to eliminate unwanted microphony.
This tube is an octal-based high mu twin triode with separate indirectly heated cathodes. It was originally designed in the 1930s as an audio frequency voltage amplifier. It is a pre-cursor to the B9A ECC series. It was widely used for input amplification in older audio amplifiers. The Golden Dragon 6SL7GT is an excellent example manufactured in China to strict UK specification and should not be confused with the inferior examples of the same tube types which are available at a lower price elsewhere but which are not considered of sufficient quality to be included in the Golden Dragon range.
This tube is an octal-based medium mu twin triode with separate indirectly heated cathodes. It was originally designed in the 1930s as an audio frequency voltage amplifier. It is a pre-cursor to the B9A ECC series. It was widely used for input amplification and driver stages in older audio amplifiers; some designers still prefer these tubes for the same application in todays designs. The Golden Dragon 6SN7GT is an excellent example manufactured in China to strict UK specification and should not be confused with the inferior examples of the same tube types which are available at a lower price elsewhere but which are not considered of sufficient quality to be included in the Golden Dragon range.
