VINTAGE SANSUI BA-2000 100 WATT POWER AMPLIFIER AS IS
I HAVE READ THAT THIS HAS BEEN CALLED THE ONE OF THE THREE BEST POWER AMPS EVER MADE BY SANSUI. THIS BEAST IS THE BEST OF THE BEST WITHOUT QUESTION. I WILL NOT GO INTO THE SPECS, I WILL POST THE SPECS FROM A TEST SITE.FIRST THIS IS AN AMP THAT WORKS BUT HAS NO SOUND OUTPUT THEREFORE IT IS A NON-FUNCTIONING AMP WITH NO RETURNS AND SOLD AS IS AS DESCRIBED. IT GOES THROUGH ALL OF ITS POWER ON CHECKS AND CLICKS AND THE RED LIGHT TURNS GREEN INDICATING ALL IS OK. I HOOKED A CD PLAYER DIRECTLY TO THE INPUTS BUT HAD NO SOUND. MIGHT BE A FUSE OR SOMETHING MORE, I AM NOT SURE. ALL LIGHTS WORK AND IT LOOKS GOOD, NOT MINT BUT GOOD. HAS A FEW BUMPS AND THE METAL CABINET HAS SOME SCRATCHES AND PAINT CRACKS.DESCRIPTION AND SPECS:Stereo power amplifier which planned whether it was the Oide power in order to reproduce the sound which the music itself has it not only to to play original sound comfort faithfully, but. The electric current through which this scheme flows into each transistor is set to one half, respectively. For this reason, the operating point with a sufficient linearity can be chosen, and also the stable Oide power is acquired continuously. Moreover, a low distortion is obtained over a wide band. Circuitry has the composition of having polished up further the pure complimentary OCL circuitry of the whole page hardwired connection, and two steps of class A amplification with an active loading in the stage of a predrive and the stage of the drive serve as a parallel push pull scheme by a three-step Darlington connection.A differential-amplification part is the combination of a constant current circuit and a current mirror circuitry, and is carrying out the direct-current balance to stability more at the same time it raises the stability of middle point potential by using the newly developed dual transistor to which the operating point and the temperature characteristic were equal. Furthermore, the parts to be used adopted positively high-class component partses, such as a low leakage type capacitor with little a super-low-noise transistor, a loss, and the leakage current, a fuse resistor, a nonflammable resistor, and a varistor, and it has determined the tone quality not only by a physical characteristic but by a strict audition testing. A right-and-left independent 2 coil toroidal type transformer is adopted as a power-source part, and the mass silicon rectifier and the mass electrolytic capacitor constitute the powerful power-source part. Moreover, ±2 power source is supplied independently to a predrive and the drive stage, and also the stabilized power source is prepared in the predrive stage which adopted the constant current circuit. The direct-current detector which carried the current limiter circuit by detection of an area of safe operation (ASO) and the temperature detector by a posister, and was combined with the speaker protection with the relay is adopted as a protection of an output transistor. While these protection functionalities operate, the indicator of the front panel lights up red. About the in rushes electric current at the time of the power source on which poses a problem with the Oide power amplifier, a relay for exclusive use and a preventing circuitry are prepared, and the security is improved. The large-sized power meter excellent in the flattery nature which can perform the checking of an Output voltage or a right-and-left balance is carried, and this power meter is an actual-value window type by a logarithmic comression circuitry, and is followed also to a pulse signal or the signal at the time of the Koide power. It changes to three steps, x1, x1/10, and x1 / 100, and this indicating range can be read from -34dB to +3dB from 0.001W to 110W. While having adopted the stream composition according to block which separated completely the driver stage, the output stage, and the power-source part, respectively and preventing the cross interferencee and influence of each block stage, each block was connected with the shortest distance and shielding wire is eliminated as much as possible. In order to diffuse an exothermic of an output transistor effectively, the chimney type large-sized heat sink using a stack effect is adopted. This heat sinker is what adopted four convectors of Envelope-Volume 1,200c.c., and makes the most of a stack effect with a kind of forced-air-cooling action of absorbing cold air from a lower.

I AM AN HONEST SELLER AND I WANT HONEST BUYERS. I DO ACCEPT INTERNATIONAL BIDS HOWEVER I ONLY SHIP TO THE CONTINENTAL US ONLY.
THIS WILL BE SHIPPED IN A NEW (USUALLY) BOX WRAPPED IN STRETCH WRAP AND STYROFOAM.
PLEASE WAIT FOR THE INVOICE BEFORE PAYING.
LIKE MOST PEOPLE, I HAVE AN 8-5 JOB LIKE MOST SO IT MAY TAKE A COUPLE DAYS TO BOX AND GET ITEMS OUT. I TRY MY BEST TO RUSH BUT I TAKE PRIDE IN PACKAGING WELL. IT WILL BE PROPERLY PACKAGED USUALLY USING BRAND NEW BOXES AND NEW STYROFOAM, NOT PEANUTS. I DO USE PEANUTS ON SMALLER ITEMS AND BUBBLE WRAP. I HAVE SHIPPED A SET OF LARGE CERWIN VEGA'S TO FLORIDA, A SET OF HPM1100'S TO THE MIDWEST AND SO ON. I HAVE TONS OF PICTURES AND VIDEOS TO SHOW THE CONDITION MY ITEMS ARE IN PRIOR TO SHIPPING.
