  • NEW two-way 6E2 magic eye tube kit, suitable for DIY enthusiasts or installed in your gallbladder power amplifier, PCB board can be fixed in any cabinet amplifier, connecting the tube seat with flying wire.
  • Two-way 6E2 tube cat-eye drive board: audio signal that enables the 6E2's screen column to follow the size and flashing, the screen glow area is proportional to the signal size, when no signal, the luminous area is the most small, strong signal. The upper and lower light bands expand from both ends to the center until they overlap, excitation in the alterging signal.The 6E2's green electric-eye screen changes with the signal, lifelike like a cat's eye.
  • The circuit of this drive plate adds a first-stage amplification circuit to the old circuit to improve Input sensitivity, input device impedance of 100K, reduces the shadow of the original circuit after access sound, the board is equipped with precision multi-turn adjustable resistance W1, W2, can adjust the input sensitivity, applicable a variety of signal options can be connected to the front-level audio signal output or the amplifier's horn output.
  • The plate is equipped with 100K precision multi-turn adjustable resistance W3, W4, which can adjust the light band open and close scale,makes the left and right channels symmetrical at static time.This PCB board is a dual panel with a small form factor, reducing the required mounting space, easy to add to the existing equipment,installation use more flexible and convenient.Bile tube wire flying wire connection, so that the PCB board can be freely fixed position.
  • Fly wire only need to connect the cat's eye tube seat 1 foot (gate pole input), 2 feet (similar to anodes, 2, 6, 8 feet inside is connected can be connected feet.Tubes are different or slightly different), 3 (ground, cathode), 7 feet (similar to curtain gate adjustable light band open and close scale, 7, 9 at the bottom of the tube seat connected).

Learn About The Tube Amps And How They Work

Chances are you’ve just bought your first Electric guitar and wish to find out all about guitar amps. Maybe you’re just curious as to how long amps have been around, how they work, or which to purchase. Whatever the reason, by reading this article, you’ll get answers.

History of the Amplifier

Guitar amps have been around for roughly 70 years now, having first appeared during the 1930s. The earliest amps had very poor high treble and bass responses. This was improved over time, as amps became better developed. During the ‘60s, the guitar amp greatly evolved to where it is today when guitarists of that era experimented with deliberately overloading their amp to create Distortion. From that point on, most amps were provided with preamp distortion controls. Playing with distortion has since become an important part of Electric guitar playing

Types of Amplifiers

There are two types of amps: solid state and vacuum tube amps. Additionally, there are some amps that combine both solid state and tube technologies. Most amps, especially the least expensive ones, are solid state because they are lighter and easier to repair than tube amps are. A lot of guitarists, however, prefer the tube amp due to the tube amp’s analog sensitivity, which they claim makes tube amps sound better. While this is probably the case, most beginners can’t afford to shell out the $500-$1000 it costs to buy a good tube amp. That’s why solid state amps are actually a good buy in some cases.

Solid state and vacuum tube amps come in combo (speakers and head) packages or separately. Guitarists who aren’t picky can just buy the combo, while those who are picky can “mix and match” heads and speakers. This is useful for those looking to achieve a certain sound.

How Amps Work/What Watts Mean

Without going into a big, long, technical explanation, amplifiers basically take the vibration (sound) of the string(s) and amplify it, thereby increasing the sound. If you wish to find out more about the technical side of guitar amps, there are several good books that cover the topic pretty thoroughly.

Each amplifier has a certain number of watts. The higher the number of watts, the louder the sound produced by the amp is. Generally speaking, those who wish to play shows will want to get amplifiers with at least 30 watts, preferably at least 50 watts, especially if they plan on playing at larger venues.
