Shun Mook Power Tubes Resonators
The Shun Mook Power Tube Resonators (PTR) use the same design principies as the mini-valve resonators. Only the physical size og the PTR is much larger due to the higher level of energy flow through the bulb. The PTR is designed for placement on top of the vacuum tube; its body is approximately 1.4 inches in diameter bu 1-inch in height.
Three silver alloy wire legs firmly hold the PTR to the top of the vacuum tube. The legs are sized at the Shun Mook Workshop for large, medium and small (1.75”, 1.5”, and 1.25” average glass diameter) vacuum tubes. However the user can bend and make adjustments to the legs to fit slight variations in different tube brands. In the case if tubes like the 300B or KT88, the legs are set for the top portion of the glass dome.
Due to the high heat output of most tubes, the PTR is treated with a special heat resistant epoxy coating, In normal operation, the wood will get very hot which means the molecules inside are excited and resonating musical energy to enhance the bulb’s performance.
The PTR is packaged in sets of two. For multi-tube power amps, it is not necessary to cover all output tubes with PTRs. Usually one or two per channel will be enough for a big improvement. It’s like upgrading your ordinary vacuum tube to those famous brand name NOS models.
For the last years Shun Mook Acoustics Inc. has introduced a new concept and a new approach to usage of material in the control of acoustic resonance in High Fidelity. There is no real magic about Shun Mook's products. They are all based on simple high school physics - "Sympathetic Resonance". As all elements in this universe will resonate when like pattern energy is generated from another material. Just as in a physics experiment when you excite a metal tuning fork of say the "A" frequency and hold it close to another static "A" tuning fork. The result is that the second tuning fork will also get excited because same frequency energy is transferred through the air to cause the vibration. Thus when the musical energy produced by any Hi Fi system will excite to different degree of all materials within the space covered by the acoustic spectrum. Different materials will have a positive or negative effect on each other influencing the final music re-production. The secret is to control and tame such resonance to the advantage of the system.
It is commonly known that many musical instruments use Mpingo and other ebony wood to create the most natural musical tones and harmonics. Just like the clarinet, the violin and other wind and string instruments uses the ebony as the essential component to generate the sound. With many years of research and development Shun Mook has designed and brought forth several revolutionary devices in the technique of electronic audio enhancement.
