Power amplifier ocl 150 watt stereo receivers

From the CA that whipped up a whirlwind and brought Yamaha recognition in the audio world, to the AXA that after groping around with digital technology managed a comeback to pure analog. Handles a wide variety of uses with its rich assortment of input and output terminals. In , there was a big shift in high-end home stereo systems from the separate components that dominated the s to new component types, and Yamaha released the first generation of component stereo, the Series integrated amplifiers. The external design was a conservative style with not even a hint of the appearance of the CA that would be introduced the next year, and the circuitry was not the latest pure complementary type, but the engineers may have been avoiding an adventurous approach for their first foray into the component stereo field.

Pioneer SX-636


These genuine "monster" units are rarely available, especially in this kind of immaculate condition. Both the exterior and interior of this beauty are as clean as the day it was first sold. Although some describe the Z as a fully synthesized digital unit, that's not quite accurate since it still retains the familiar analog FM dial.

The Z was the culmination of Sansui's highly respected technical expertise and came right after their wildly popular G-Series units the Z is actually the evolution of the G series. The nearly non-existent THD of 0. Because Sansui put all their very latest technology available at the time into the Z, it definitely earns its place among the top 20 of the most powerful receivers of the era.

It's rated at an honest watts per channel 8 ohms with onset of clipping at about watts per channel. The power consumption of this unit is about watts The overall beautiful design of the Z includes the heavy gauge brushed aluminum faceplate with a beveled window for the analog dial and a rosewood veneer case.

The multi-colored LED readouts for the power meters, station numbers, frequency analyzer, FM tuning and volume control creates a dazzling light display in low light situations. The tuning knob has optical detectors for digital tuning along with a convenient window that guides you to the exact point of best signal reception. However, it's extremely accurate with its touch control pads and the LED volume level is right there above the pads; it's nearly impossible to have any accidental "slip-of-the-fingers blast" of volume when using the pads.

It's actually pretty cool! It has that certain "look" That was mo' money than the competing 40 watters at the time. Forget that 40 watts per channel, this excellent unit has tons of headroom. Lab tests showed the onset of clipping at 62 watts per channel.

Note: another of our personal favorites, the beautiful Sanyo was one of R's main competitors at the time. They are both similar in design The first thing that grabs you about the Scott is the gorgeous design This unit has all brand new lamps that cast the right look into the black background meters Similar to other receivers, the switch had double-duty; it also was the speaker selector and, eventually, because the switch was ill-designed and incapable of handling the power load over time, it would arc itself into oblivion.

The good news: this unit has a professionally re-designed power switch that completely circumvents the original switch and you simply use the speaker selector switch as normal. It looks like a factory installation, it's that good.

About H. Hermon Hosmer Scott held many patents and was instrumental in the birth and development of high fidelity sound equipment. HH Scott, the famous name by which he and his firm were so widely known, became one of the top two respected names in consumer high fidelity and later stereo , the other also bearing its founder's name, the very famous Fisher Radio.

HH Scott was one of those highly respected companies in HiFi that spent relatively little on advertising but in the audiophile community they were well known regardless. These were designated for distribution primarily in Europe although obviously some made it to the USA.

Designed and built entirely in-house by Rotel, this unit has a very high quality DC configuration along with quartz locked tuning. The black, solid iron rack handles do exactly what they were designed to do: you can pick this heavy 37 lb unit up by the handles without hesitation, no sweat.

The glossy black faceplate has attractive white silkscreen lettering to identify all the selections and functions which certainly has a dramatic and attractive appeal.

Besides it's stunning design that includes Rotel's trademark "slash-cut" glass there's no doubt the RX definitely has plenty of headroom beyond its conservative power rating of 75 watts per channel 8 ohms. It drives 4 ohms with ease as well. Like most of the later Rotel units with digital power meters, the meters tend to get testy at times.

However, there is a button to change the tempo of the meters. Although we prefer analog meters, Rotel like everybody else in the 80's made the switch to digital. They also included a small-ish unobtrusive digital LED radio station readout window but, fortunately, they also kept the "normal" analog tuner with the needle sliding along to the different stations with a spin of the tuning knob.

The digital quartz lock kicks in after watching the LED pointer arrows guide you to go left or right until the green light comes on. About Rotel Rotel is a family-owned Japanese manufacturer of high end audio and video equipment. The company was established in Rotel was one of the few Japanese audio companies to create, design and manufacture their products in-house instead of using sub-contractors.

They didn't advertise to the extent of the other big names in Japan, they relied on targeted marketing towards audiophiles and higher end audio related publications. It was his very first step into HiFi. Even though he took very good care of it, we still gave it a complete tear-down and servicing as usual. Like all of the receivers in this well-built series , , , etc , the has great reception capabilities and the sound is excellent. For those who first ask "how much power does it have?

The Sansui is an IC-equipped stereo receiver with advanced circuit board module CBM construction that yields superb electronics which was made available in the mid 70's at a modest price. The has high-gain IC integrated circuits in the tuner sections and phono equalizer. In reality, you can expect about 20 watts per channel driven into Hz with extremely low distortion. Even at that low wattage the Sansui has enough power to drive even large stereo speaker systems.

As they say in just two words: outstanding performance. This series of high quality Sansui audio components soon became legendary for their outstanding build quality and good sound. Essentially, Sansui receivers from the 70's have a warm tube-like sound that a lot of other brands just don't have. Sansui was a premier manufacturer of high-end audio components that arguably peaked in the mid-to-late '70's.

Sansui power amps, integrated amps, receivers, tuners, loudspeakers, etc. Founded in Tokyo in , Sansui initially manufactured electronic parts. By the s, they had developed a reputation for making serious audio components.

They were sold in foreign markets through that and the next decade. Sansui's amplifiers and tuners from the s and s continue to remain in high demand by audio enthusiasts. The Champagne series from Pioneer marked the turning point from cool products to computer controlled gizmo receivers but at least it was before the beginning of the end when Pioneer and the rest of them turned to black plastic and home theatre.

Essentially, at 45 watts per channel, the SX-6 is a computer controlled, fully synthesized and digitally controlled receiver. However, it's still a quality Pioneer unit that also featured their "non-switching amplifier" technology. That was normally reserved for the higher end Pioneer receivers. It yields a very low THD of 0. About Pioneer Pioneer Corporation Paionia Kabushiki-kaisha commonly referred to as Pioneer, is a Japanese multinational corporation based in Tokyo, Japan, that specializes in digital entertainment products.

The company was founded by Nozomu Matsumoto in in Tokyo as a radio and speaker repair shop, and its current president is Susumu Kotani. Timeline: Pioneer's founder, Nozomu Matsumoto develops the A-8 dynamic speaker. May Fukuin Denki is incorporated. June Company name changed to Pioneer Electronic Corporation. Pioneer played a role in the development of interactive cable TV, the Laser Disc player, the first automotive Compact Disc player, the first detachable face car stereo, Supertuner technology, DVD and DVD recording, the first AV receiver with Dolby Digital, plasma display and the last 2 years of plasma models were branded as Kuro , because of their outstanding black levels.

The company works with optical disc and display technology and software products and is also a manufacturer. In March , Pioneer stopped producing televisions as announced on 12 February On June 25, , Sharp Corporation agreed to form a joint venture on their optical business to be called Pioneer Digital Design and Manufacturing Corporation. It has been retrofitted with an absolutely stunning solid teakwood case to create a unique, one-of-a-kind vintage piece. It also has jumpers so it can be used as either a standalone amp or preamp.

As the Vintage Knob eloquently stated: "Sony's mid-end receiver back when model lineups got multiplied with frenzy. Also soft-touch buttons, 3-level auto-tuning selector with or without muting and eight tuning presets with pre-cut name cards plus side slider so that your memory doesn't fail. And, as with So much so that Gradiente in Brazil even made a rebadge of the V55 named the M with obvious cosmetic parts sharing but completely different circuits and internals.

This "same-but-not-same" makes the financial advantage of the rebadge thing vanish entirely but multiplication was the trend so these share some but not all And a high-gain low-noise phono amp in the preamp section enables you to even use an MC cartridge with your turntable to capture the subtleness of the softest, most delicate music. It's also important to know that an efficient, compact Pulse Power Supply provides stable DC power even at peak levels.

And highly responsive Hi-fT power transistors artfully reproduce complex wave forms even at high frequencies and full output power Main specs: Frequency response: 5Hz to 40kHz THD: 0. About Sony Nothing to add here, Sony is one the most well known electronics companies in the world. In excellent condition and often overlooked because it looks very different from the "typical" vintage receivers of the era, the JVC R-S33 was the middle of the line receiver for JVC in At the time, class "A" hybrid amps were a bit of a trend in this era.

By feeding them sinusoidally-varying reverse bias during their half-cycles of non-conductivity, output transistors never switch off. No switching distortion as in normal Class B, no useless heat production as in Class A. When lit up it's got a beautiful green glow to the tuning display. The walnut side panels add a touch of class to this very excellent receiver. It's a sleek, beautiful build consisting of an all-aluminum front end, real glass window for FM, wood side panels, analog tuner with incandescent lamps along with LED power output meters and a combination of knobs and slider controls.

They pressed the very first record ever The quality of their vintage gear is mostly first rate and under the radar type excellent value. Home page. Sansui Z.

With a more amp-like front panel than many of its competitors, the Kemper is the best amp modeler for players who want to be eased into the simulation experience, hiding a huge amount of depth behind its simple user interface. This 18V swing occurs when the input voltage changes uV. Here is a simple audio amplifier for receiver projects. The datasheet of LAA recommends a The op-amp is one of the most common and successful op-amps in the history of manufacturing. Costas Sarris believes in building simple tube amplifier designs, with simple circuits that he found to work better, particularly when the electric signals carry music information, because the signal distortion is easily handled. V 0 is the output voltage; V 1 and V 2 are the input voltages; A d is the gain of the amplifier i. Simple Metronome.

This is my second encounter with LM I was pleased with the sound this chip produced the first time, so I decided to make another amplifier with it. The schematic is based on the schematic in the datasheet of the chip with minor changes. I made the output inductance L1 by winding 15 turns of enameled wire around the resistor R7. The diameter of the wire must be minimum 0.

To make the stereo channel amplifier, build the similar amplifier circuit only and connect to the power supply using parallel connection with another same amplifier.

The important factors that need to be considered while designing a audio amplifier is gain,noise, frequency response and distortion. Its the most common and best way to do this. The complete circuit diagram for Dual Channel Pre-Amplifier consists of two mono circuits combined to form one stereo circuit as shown in the image below. We can take the low input signals from the audio jack of smartphones or PCs Rangkaian penguat yang menggunakan transistor dikenal sebagai penguat transistor. Oh, wait - do you mean help you design one? What are the requirements? For headphones? Can you use any other transistors PNP?

20 Watt power tube amplifier diagram use the tube of EL34, this is mono amplifier, build similar circuit will make it stereo. The two most common are the.

This is the cheapest Watt amplifier circuit you can make,I think. Enough for you to get rocked? TIP and are complementary Darlington pair transistors which can handle 5 A current and V ,famous for their ruggedness.

This tube amplifier designed in and worked from until Two-OpAmp Broskie auto-bias circuit. The output stage of the circuit is a Cathode Follower and is suitable to drive a low impedance amplifier. Note that a single 1M resistor is missing from the voltage reference portion of the circuit; in its stead, a 10M and 1. One of the mods he suggested, deleting the V zener to the SRPP front end, would have caused serious problems with these amps.
