Tube Amplifier

The Tube-Tech PE 1C Program Equalizer is the design that started it all for John Petersen and Tube-Tech. It s an all tube version of the legendary Pultec EQP 1A, an equalizer that was, and still is, known for its uncanny ability to make things sound better by just running signal through it. Has Tube-Tech captured that magic? Just do a Google search for Tube-Tech PE 1C. Page after page of world class and mid- to upper-level recording studios come up. That alone tells the whole story. Tube-Tech PE 1C Program Equalizer, First Take: Passive Pultec-style EQ Tube-based gain-makeup amplifer Balanced I/O and Floating TransformersPassive EQ The PE 1C contains a passive filter and a tube-based amplifier to restore the loss from the filter. The filter has a low frequency boost/attenuate section with 4 selective frequencies, a high frequency boost section with a variable bandwidth and 10 selective frequencies and a high-frequency attenuation section with 3 selective frequencies. The filter is placed directly after the input transformer therefore eliminating noise from the amplifier when boosting either low or high frequencies. The amplifier consists of two tubes (valves) in push-pull configuration (one ECC 83 as the pre-amp and phase splitter, and one ECC 82 as the output stage), and an output transformer. Both input and output are balanced and fully floating. The in/out key switches the filter in and out without clicks and changes in level, while the amplifier remain in the signal path.Balanced I/O and Floating Transformers Input and output are balanced as well as fully floating. This provides maximum electronic isolation for superior noise rejection. The power supply for the pre-amp and phase splitter are stabilized and the heaters of both tubes (valves) are fed with a stabilized DC voltage. This prevents any variation in the DC energy when combined with the musical signal, which would otherwise cause certain types of distortion. Put simply, the PE 1C s DC-stabilized circuits keep the EQ bands free of any unwanted artifacts. EQ is smooth and distortion-free. About Tube-Tech For over twenty years, Tube Tech has been one of the most prominent names in all-tube signal processing equipment. You ll find their gear in the best recording and mastering studios around the world. The company s founder, John Petersen is an electrical engineer who was factory trained at Solid State Logic, EMT, Studer, Sony, Neumann, and NTP Electonik (digital audio routers). He also designed tape recorder playback/recording amps for Lyrec tape recorders (found in the studios of the legendary Joe Meek and Vangelis). His first design under the name of Tube-Tech was an all-tube equalizer based on the legendary Pultec EQP 1A. Petersen continued to design and manufacture a number of innovative all-tube outboard processors including preamps, multiband compressors and summing amps. Thanks to John s dedication to high-quality analog sound you ll see Tube-Tech gear in the racks of pro audio le

Looking for midrange punch as only tubes can deliver? Look no farther than the Tube-Tech ME 1B Midrange Equalizer. Based on the example of the legendary Pultec MEQ-5 from the days of yore, Tube-Tech has dedicated a modern EQ to this all-too-important region of the audio spectrum, and does it with all-tube style and warmth. It provides the kind of performance you expect from a high-end EQ, and does it effortlessly. With Tube-Tech EQ, you get dramatic results without having to tweak endlessly. To get the most out of the ME 1B, use it to focus on midrange while another EQ, such as the EQ 1A handles the lows and highs. And while it would be tempting to use it to make individual instruments larger than life, adding punch and sheen to an overall mix is where this EQ shines. Tube-Tech ME 1A Midrange Equalizer, First Take: Midrange program equalizer with passive filters and tube-based gain-makeup amplifier Three sections of selectable EQ Balanced and fully floating I/OPassive EQ with Tube Amplifier The rackmount Tube-Tech ME 1B Midrange Equalizer contains a low frequency boost section for peaking, a mid frequency attenuation for dipping, and a high frequency boost section for peaking. The ME 1B contains a passive filter and a tube-based amplifier to restore the loss from the filter. The filter has a low frequency peak section with 5 selectable frequencies, a mid frequency dip section with 11 selectable frequencies, and a high frequency peak section with 5 selectable frequencies. The filter is placed directly after the input transformer, therefore eliminating noise from the amplifier when boosting either low- or high frequencies. The amplifier consists of two tubes in push-pull configuration (one ECC 83 as the pre-amp, and one ECC 82 as the output stage), and an output transformer. Both input and output are balanced (600_) and fully floating for maximum electronic isolation. The in/out key switches the equalization in and out without clicks and changes in level, while the amplifier remains in the signal path.Three Frequency Sections Using a bell curve EQ to isolate center frequencies, the ME 1B divides the midrange into three sections, low, mid, and high. The low frequency section comprises a continuously variable peak control (0dB to +10dB) and choice of five selectable frequencies (200Hz, 300Hz, 500Hz, 700Hz, 1kHz). The Mid Frequency section comprises a Dip control that is continuously variable from 0dB to -10dB and eleven selectable center frequencies from 200Hz to 7kHz. The High Frequency section covers five selectable frequencies from 1.5kHz to 5kHz and a Peak control that is continuously variable from 0dB to +8dB. Balanced and Fully Floating I/O Both input and output are balanced (600 ohm) and fully floating, which provides maximum electronic isolation since there is no common ground between input and output. Input and output transformers come with a static screen between the primary and secondary wirings. These screens shield the secondary from th

Traveling wave tube amplifier - A traveling wave tube amplifier (abbreviated TWTA and often pronounced "TWEET-uh") is an electronic device used to produce high-power radio frequency signals. The bandwidth of a broadband TWTA can be as high as one octave, although tuned (narrowband) versions exist, and operating frequencies range from 300Â MHz to 50Â GHz.

Automotive vacuum tube amplifier - Vacuum tube radios and amplifiers were used in cars until being displaced by transistorized radios. This shift occurred for the same reasons as in almost all other electronic devices: transistors are smaller, cooler, cheaper, more durable, and more precise.

Valve amplifier - A valve amplifier (British and Australian English), also known as a tube amplifier or vacuum tube amplifier (in American English), is a device for electrically increasing the power of an electrical signal, typically sound.

Crossed-field amplifier - A crossed-field amplifier (CFA) is a specialized vacuum tube, first introduced in the mid-1950s and frequently used as a microwave amplifier in very-high-power transmitters. A CFA has lower gain and bandwidth than other microwave amplifier tubes (such as klystrons or traveling wave tubes); but it is more efficient and capable of much higher output power.
