Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

Super flexible and powerful Lucasfilm THX rated theater amplifier from McIntosh.
6 x 100 Watt amplifier channels in a single chassis!

*Note that a current McIntosh home theater amp will set you back over $7k

You can configure this beast in the following configurations:
• 3 x 300W for 3 channels total
• 4 x 100W and 1 x 300W for 3 channels total
• 6 x 100W for 6 channels total
• 2 x 100 *AND* 2 x 300 for 4 channels total)

Condition:
The 6 x LED VU meters, not activated in the pictures, are simply gorgeous and very useful. There is also an adjustable display brightness control as shown on the back panel photo in this listing. 

This unit, like almost all other McIntosh units, uses a front glass face plate which provides an attractive and very durable finish. The lettering will never show wear. 

This particular sample is in super clean condition without any noticiable scratches or blemishes. It has been fully tested in our lab to manufacturer specifications. 

It comes in its original McIntosh box and includes an original copy of the owner's manual and a power cord.   

Cosmetic Notes:
• Some of the red binding posts have cracks in the plastic from age that do not affect functionality.
• Light cosmetic blemishes including a black vertical mark in the channel four meter

This MC7106 will ship in an authentic McIntosh double box for safe transport.

The SkyFi Testing Process for Solid State Amplifiers:

We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR.

If the amplifier passes visual inspection, we move on to a controlled power on sequence using a Sencore safety analyzer to monitor current draw in real time. Once the amplifier is determined to be safe to operate, we connect it to full AC mains for function and power testing. We connect the speaker outputs of the amplifier to a Sencore PA81 Power Analyzer which acts as a dummy load, DC offset monitor, and oscilloscope interface. We start with a low level 1KHz test signal at the amplifier’s input and slowly increase its amplitude while monitoring the output on an oscilloscope for signs of noise, clipping, distortion, or improper channel balance. We continue increasing the signal level until the amplifier reaches clipping. At this point we take an output power measurement and compare it to the spec sheet of the amplifier to verify proper performance. If the device under test has both balanced and single ended inputs they are both tested at this time. We finish off the bench evaluation with a 1KHz square wave check and a 20Hz to 20KHz sine sweep to assess the amplifier’s frequency response characteristics. This battery of tests will usually reveal if the amplifier has any issues that need further attention.

Before the device leaves the bench, we perform a listening test with actual music using a variety of preferred test tracks. Our benches are outfitted with familiar monitor speakers which help us identify inconsistencies that will not always show up on our test gear. The main things that we are listening for are hum or noise with no signal present, proper center image, clicks, pops, or any other obvious undesirable audio characteristics.

If the unit passes all of these tests it is moved to our long term testing rig where we simulate real word operating conditions for 6-8 hours. This allows us to monitor the unit for signs of thermal runaway or intermittent issues that only crop up when the unit has fully come up to temperature.
