Beautiful, Fully Serviced Mcintosh MC2200 Power Amplifier, with McIntosh, Non-Panlick Walnut Cabinet, 30 Day Warranty, Professionally Packed by McIntosh Service Center for Shipping! Cosmetic Description:8.5/10 The Power Amp is in excellent cosmetic condition with little visible cosmetic wear. There is a small nick on the front faceplate, in the upper right corner (please see the photos as they are the best description).The McIntosh Walnut Cabinet has a couple of light marks on the left side but is otherwise beautiful. It is in outstanding condition for nearly 50 years old. Overall - the cosmetic condition will please even the most discerning audiophile. Service Work / Operation:(10/10): While we dont know all of the service history on this unit, it appears to have been refreshed about 6 or 7 years ago. Without opening up the unit completely and checking every part on every board, the extent of that work is impossible to know. It appears to have had a conservative refresh, replacing what needed to be replaced - not a restoration. The Filter Caps are High Quality Cornell-Dubilier USA Made. It was just completely checked, cleaned, serviced and bench tested for 48 hours at Stereo Fixers, Inc. in Boca Raton, FL - a McIntosh Specialist. It performed flawlessly, and comes with a 30 day Parts and Labor Warranty. Stereo Fixers, Inc. will Professionally Pack the unit for Shipping with Full Value Insurance (a $150 value) If youre not familiar with this particular McIntosh Power Amp, here is some additional information we were able to gather from the internet: The McIntosh Mc2200 is a Stereo Power Amplifier with a unique power guard circuit, equivalent to the MC2205 (without power meters.) Distortion is eliminated by using a low-noise monolithic transistor differential amplifier at the input side of the power amplifier circuit, which provides both input and feedback signals. The next stage circuit is a voltage amplifier circuit with Class-A operation. The driver circuit and complimentary service circuit are designed to operate close to Class-A to reduce crossover distortion. The circuit is always designed to be moderately biased against changes in temperature. The power transistor is Class AB operation and the bias current is secured by a thermistor. The output-stage employs a single-ended para-push method and consists of six highly reliable complimentary service power transistors. Since this circuit is a balanced emitter-follower connection, it has outstanding stability and low distortion. Moreover, the unique output-bias circuit realizes Class B operation without crossover distortion. The output signal of the MC2200 passes through an output transformer, which is designed to match the output terminal of any impedance so that the maximum output is obtained for all frequency signals regardless of the output terminal. This transformer also protects the speakers in the event of an amplifier failure. When a DC component is mixed into the output, the transformer eliminates the component and prevents damage to the speakers. To prevent overloading of the output transistor, the output signal is always monitored by a McIntosh proprietary monitoring circuit. This circuit becomes high impedance when the output level exceeds the rated value, but this has no effect on the output. When the output reaches its maximum value, the monitoring circuit limits the signal supplied to the output transistor to prevent shorting of the output of the amplifier or damage to the output transistor. This monitoring circuit monitors the plus and minus sides of the output signal separately. In order to improve the stability and sound quality of reproduced sound, it is equipped with a Power Guard System which is a unique new circuit. In this circuit, the Normal (green) and Limit (red) lamps on the front panel are operated by a waveform comparison circuit unique to McIntosh. This circuit electrically compares the output waveform with the input waveform, and when the difference between them becomes 0.5%, the Limit lamp turns on and the Normal lamp turns off. When the difference reaches 1%, the Power Guard Circuit operates to prevent clipping of the amplifier preventing distortion from being reproduced from the speaker, while at the same time protecting the speaker. In this case, the amplifier still exhibits the rated maximum output. The input waveform and the output waveform are compared by an IC differential amplifier, and the waveform difference due to distortion of the output waveform is converted into a voltage. This voltage is amplified approximately 100 times supplied to a Schmidt Trigger Circuit through a full-wave rectifier circuit. The Limit Lamp also lights up when the amp is overloaded. Even if the overload condition is very short, the lamp remains on for a period of time that is sufficiently visible. In this case, the meter displays less than 200W. Again, the voltage obtained from the waveform difference is used. If the voltage becomes higher than the level that turns on the Limit Lamp, the Power Guard Circuit is activated. When using a Power Guard Circuit, set the power guard switch on the rear panel to the Normal Position. When this switch is in the out position, only the Limit Lamp operates.

McIntosh Mc206 6 Channel Power Amp 120w X 6. The MC206 seems to be in great working condition. I am the original owner, and it has always worked perfect. I sent it a few years ago to the legendary Terry Dewick for display light replacement and a general check out. Nothing that I know of is wrong with it. I hooked it up to my new AVR and tested all channels.I have the McIntosh factory box to ship it in. I will only ship to the 48 contiguous States and like to use Fedex. Shipping cost will be determined by the buyers shipping address and paid by the buyer. It is a great amp, but I am downsizing so to speak. My McIntosh Preamp failed so I bought a new all in one AVR so no longer needs individual amplifiers. I am now retired so scaling down.I have a PayPal account I would like to use for payment, If paying by check I would make sure the check clears before shipping. If you have any questions please contact me.

Nobsound Little Bear MC2 Mini Fully-Balanced/Single-Ended Passive Preamp; Hi-Fi Pre-Amplifier; XLR/RCA Volume Controller for Active Monitor Speakers (Black) The Best Choice for Active Speakers More and more audiophiles find that the behavior of normal multimedia speakers cannot meet their demands, and then they choose professional active monitor speakers. However, this kind of speakers usually doesnt have a volume controller, which means a pre-amplifier is needed. Active monitor speakers are mostly placed on the desk and used for near field listening. So they need to consider the area required for Hi-Fi pre-amplifiers (normally very big). Whatmore, different pre-amplifiers may differ in their timbres and this is the most bothersome issue. As an audiophile brand, Nobsound decided to solve this problem and designed this product. Its small size wont take much place and its clean silver color suits for various usage scenarios. There is no amplifying circuit in the device and wont change the timbre, while the amplifier in the active speaker is enough to drive it. With this product, you can enjoy the most original timbre and quality of the speakers and wont be trapped in the selection of pre-amplifiers. Specifications: Dimension: 148 x 48 x 80 (mm) Weight: 0.6 (Kg) Impedance: 20K? Input: RCA / XLR (selection switch) Output: RCA / XLR (selection switch) Package: 1 * pre-amplifier This product uses high quality fully-balanced potentiometers, NEUTRIK XLR, -Singnal RCA. Nobsound never be stingy in the components and materials of our products. This prodcut has a small size, while is still euipped with commonly-used interfaces. There is a selection switch which you can choose the fully-balanced or single-ended audio signal mode, as well as the output or input mode. This prodcut has no amplifying circuit and wont change the timbre. You can enjoy the most original sound of your active monitor speakers.
