VOX AC30H2 Heritage Collection 30 Watt Handwired Guitar Combo Amplifier
|
|
|
Rather than just a typical reissue where a vintage amp is dusted off and copied, this amplifier, like the others in the Heritage Collection, transports you through the golden age of VOX tone, combining the prized EF86 preamp channel of 1958 with the 1963 Top Boost channel all in one amplifier. Add in some modern tone shaping control enhancements and the result is perhaps the finest VOX amplifier in the company's 50 year history. Channel 1 is the EF86 Preamp channel, and features two inputs wired in the traditional way providing a 6dB gain difference between them. A two-position BASS SHIFT switch is included, with position 1 voiced to the original vintage-correct bass response and position 2 voiced to tighten the bass response and reduce any muddiness during high volume use. The three-position BRILLIANCE SWITCH provides flat response when in the OFF position. Position 1 is a new position voiced like the early AC30 Treble" amps, while position 2 is the original brilliance circuit, which acts as a dramatic bass cut. The EF86 Mode switch re-configures the EF86 valve from Pentode mode to Triode mode. Triode mode will give a lower gain tone with higher headroom. Pentode mode is the famed original mode and has a very sweet high gain tone with less headroom. Channel 2 is the Top Boost Preamp channel. Like Channel 1, this channel includes two inputs wired with a 6dB gain difference between them. The Treble and Bass controls are from the 1963 Top Boost circuit and are extremely interactive. Very minor adjustments of these controls can yield dramatic changes in tone color. And true to VOX form is the Top Cut control, which cuts high from either channel end as it's turned up. Flexible power. The O/P Switch adds even more flexibility to the AC30 Heritage. This switch changes the power output valves from Pentode Mode, which is the normal operating mode of the power amplifier, to Triode Mode which halves the

Gerber Triode Headlamp White LED Green Body
|
|
|
Heads turn when you show up after dark wearing Gerber's versatile Triode headlamp. After all it looks as good as it illuminates the trail ahead. And it illuminates like the dickens thanks to a trio of intensely bright L.E.D. bulbs. Especially when it's set on the higher of its two brightness modes.We describe it as versatile because the Triode can be worn on the adjustable headstrap Gerber includes or it can clip comfortably and easily to your cap or vest. It's really just a matter of your personal preference.The Triode gets its power from the lone AAA battery we include with purchase. The L.E.D. bulbs sustain peak brightness for longer periods casting a wash of light out some 50 feet and never need to be replaced. Three L.E.D.s never burn out or break Clips to bill of hat or use headband Light pivots up and down Light Source Type: Regulated L.E.D. Light Source Quantity: 3 Light Source Life: Lifetime Output Color: White Output Color Modes: white Configuration Modes: bright steady white dim steady white Housing Material(s): ABS Resin

SCHIIT Valhalla Single-Ended Triode Headphone Amplifier
Sale Price: $349.00
|
|
|
Valhalla is a Class A, single-ended triode headphone amplifier with no overall feedback and noninverting circuit topology. It provides classic tube sound and can drive headphones with impedances as low as 32 ohms.
Yes, we know that all you got out of the preceding paragraph is probably, "Classic tube sound." And if you're not a tube junkie, you might not even know what that means. Well, let us explain. Tube sound is a smoky nightclub with a hot chick in a red dress, it's a warm swimming pool in summer, glowing green against the purple twilight, it's a . . . well, hell, you can't really explain tube sound. Think "smooth, fluid, liquid, alive." But not in a SF-movie-gonna-eat-you kinda way. Valhalla delivers warm, magical sound for most headphones, as long as they aren't less than 32 ohms.

All About Horn Loudspeakers
One of the oldest forms of loudspeakers are the horn loudspeakers that not only provide pure, high efficient, natural music but also fast and accurate transient response.
Basically what happens in the horn loudspeakers is that the diaphragm that is run by an electromagnet is supported by a horn, which improves the coupling efficiency between the speaker driver and the air. However, the horn is like an acoustic transformer that usually gives impedance matching between the diaphragm material and the air, having a low density. This will show the difference in density and motion of the air and of the driving element.
The first horn speaker that was invented looked very simple. It was a horn attached to a receiver and the sound quality was just awful. But it was better than that of the triode tube that was the base concept behind the horn speakers. Actually, this triode tube amplified the electric signal to the possible level and it could also produce audible output while driving the receiver. But the output power was really low. And later this conception gave birth to high efficiency loudspeakers, which produced high sound pressure level. It was in 1927 when Wente and Thuras, two Bell Laboratory engineers invented the compression horn driver, or rather say a driver.
Talking about the qualities of horn loudspeakers, the first thing that attracts is the harmonic, distortion less sound. It also offers a dramatic increase in dynamic capability in comparison to other such speakers, which suffered from dynamic compression. Horn loudspeakers have the capability to run efficiently with low powered amplifiers like single ended triode amps. Moreover, they can be designed to reproduce a wide range of frequencies using a single and small driver.
But the problem with horn speakers was that they were quite big and heavy. And soon after World War II more powerful and portable systems came into the market. But it will be wrong to say that they were completely out of demand because, although the horn loudspeakers lost the major demand but they survived in movie theatres.
These speakers are used for audio application due to the fact that horn reduces the need for exotic speakers. They are even used by audiophiles for sound reproduction. But there is a fact that not all type of horn speakers are used for this purpose. As there are ample designs that differ in length, material, drivers and many such things, so it is very confusing to state that which form is the best.
Horn loudspeakers are also used for public address and concerts. As it is mentioned earlier they provide high sound pressure level that is basically necessary for sound reinforcement and thus used for public address applications. They are used in concerts due to the high volume bass reproduction so that the bass can be heard as well felt by the concertgoers. And for this reason sometimes multiple loudspeakers in a group are used. But it should be noted that they give the same benefit as a single horn loudspeaker with a big mouth area. But off course, it should include greater power of multiple drivers.
