Made with the 845Class Atube single-ended amplifier Test Price: L] Genkj (surprise) c Ⅱ Machine: l4000Yuan L] MaJ [k (deer force) power knocked 900O per L] NKe “dh (Qi Hui) tone toolbox: l] 50O million One foot of the Class Asingle-ended tube amplifier more products, which are nicknamed the \ A class of single-ended amplifier, not only rich in harmonic accounts, and the output power up to 30W Pi right, described as two foot base of its beauty.recent HNasu, good men of the radio magazine published in 845single-ended amplifier, the circuit simple, made of single-ended power amplifier device class station pit.its rated power output of 24W ~ 4W, sound wide] extraordinary, wide frequency response, deep love for foreign enthusiasts, are recommended to alarge number of readers, I wish to Iplay athrowing bricks silicon results.Figure 1shows the 845single-ended Class Apower amplifier circuit hoard solid platform in the pit are given L-channel power amplifier circuit, tory burch outlet, R Road, finished the same two-channel electrocardiography [supply with power amplification units Pressure from high-level direct thermal fat tube 845Tam Oj pole snapped Won Bin - a bag either.A class of power amplifier output II1call wave frequency Tian Tong and gate input waveforms completely similar to playing this purpose, ugg boots uk, the second power amplifier tube for jto be J-gate voltage characteristic curve of ascreen flow center J! [line section.l mounds with negative gate self bias by way of the gate on the sample tube amplifier Qu push the maximum power carry positive half cycle, it will exceed the specified value arbitrarily negative gate: Mi Zhou negative it does not achieve the flow characteristics of curved-screen}; f1A sub-class client list of lost articles caused the screen very load amplifier stage resistance and work of great beauty blog-like system.When the negative resistance is too high cut.Although the audio voltage increased, but the output power is rounded down; load impedance is too low, tods leather shoes, the amplifier tube into the bend homes for causing distortion.845Transistor 1700 [anode resistance], ugg boots sale, the usual load impedance should be taken very resistance screen 34times, so take aload impedance of the machine 7000n.Single-ended Class Apower amplifier output transformer primary circuit has internal DC through (845triode tube anode current of 8090mA), in order to make the output transformer in the larger current through the magnetic core within the saturation does not produce leaves, so the output transformer core should have enough rich content.at the same time to ensure that rrate of fire ring of blood volume device characteristics.by seeking Line package distributed capacitance as small as possible, and take care of the primary inductance of the coil over Du 20H, so as to ensure the amount of stretch of low-power amplifier power amplifier stage if the tube sound with friends and other direct thermal 2f 1.800801Wu also cho transistor, bu tbecause of the small tube sheath power consumption.shallower negative gate.The output power can only reach 20w or less.end of class Apower amplifier stage driven by avariety of ways, such as the pit stop coupling transformer coupling desktop desktop cathode output directly coupled desktop shame.This machine is used in single-ended transformer and capacitor coupling units composed of Lc way, its purpose is to promote the tube to the screen to get ahigher voltage and current that will allow blind enough The intensity level output more to promote promote the level of the machine as used 6S4Aj very tube, tods discount, the tube is asmall thumb-type electric tube nine feet of its electrical performance characteristics and 6c6, 6c76N6other similar tubes, hydrazine voltage is 300v.current 7l2mA.Marceau “Fruit 6PI, 6P6and other small power requirements emitter tube search extremely pipe connection also-and some of name brand tube amp set by 30OB, 2A3and other blood tube as thermal power pole push tube, of course, more pieces of input effects The role of class Sik foot Shi weak electrical signal to release the amount.Upon desktop machine using resistance-capacitance coupled release.with ahigh input impedance, cheap tods, output mA pair of anti-business features also.As input negative pole cut braided tube high resistance selection 1OOkn, so the current changes very weak screen, which will produce avoltage change than others, p90x workout schedule, open to more people like the voltage was increased salt.The machine used in the input stage where the coefficient of discharge tube 12Au7_ the world avery strong set Ren, with moderate gain, the input dynamic range of people blog, good linearity and low distortion characteristics of the virtual . such as the use of bipolar amplification factor of the island tube l2×7, l2AT76D so or not, Shop Tods, gain and signal to noise ratio has increased, but the input Chi smaller dynamic range, but also alittle too much distortion.To ensure the prompt ounces whole and pure tone response characteristics, war does not increase the release device that most of the negative feedback loop network.old at all levels to improve the amplifier gain.put who failed to control levels in the current negative and single-class anti -bend to keep the whole high-gain pure enemy.circle 2is the amount of 845single-ended amplifier frequency response curve to the amount of cho towel ring features a20kHz to see the amount from the 2OHz rate of gain influence changes in the blood within less than a2.5dB; 10flz a1OOk1] z range of the amount of gain change rate is less than a75dB.GIO More articles related to topics:
