We have for sale a paper original factory service manual for a McIntosh MC-3500 and MI-350. Generally clean unless noted otherwise. Please read below for details: We are selling off service manuals from our old shop and that of another friendly competitor from the area. These were both very active repair shops in their day and the manuals got used! We will try to point out any flaws we spot other than ones visible in the pictures. There is often writing in the manuals but generally it is helpful service information to help fix a quirky problem a technician encountered while working on the unit. When it says service notes on back page or see bulletins on the front cover it doesnt necessarily mean they are in this manual! Often the bulletins were kept elsewhere in the shop. PLEASE MAKE SURE THIS MANUAL IS AN EXACT MATCH TO THE COMPONENT YOU HAVE! Sometimes manufacturers will have more than one product out with similar but not identical circuitry, If youre unsure please ask questions first. We are unable to respond to requests for specific manuals. I will list more as I have time but Im still actively busy with other parts of what is now a one man operation. Sorry but local pick-up is NOT available at this time! Note that E-Bay is now collecting sales tax for the home state of the buyer. Thanks very much for looking.

Relisted due to non-paying bidder.Please read my description carefully before bidding. I will ship the item worldwide and will accept return if you pay the shipping cost.This is an original McIntosh Amplifier Model MI-350 in excellent working condition. The best of McIntosh amplifier ever built. Deployed by Gordon Gow during the Woodstock Concert in 1969 and used by many world famous rock bands such as The Grateful Dead and highly respectable studio like Skywalker Studio at George Lucas Skywalker Ranch. Due to its rust and scratches on the front face plate, I decided to buy a new MC-3500s face plate (bought from Audio Classics, New York.) to replace it.

(McIntosh Model MI-350 and MC-3500 are both the same. MI-350 was marketed as a public address sound system (concerts, high parks, or studios) and MC-3500 was marketed as a home-based amplifier. Even though their designs were both the same, MI-350 was the real rare items.)Comes with its original power cord (very rare), service manual, handbook and papers and warranty card which has Frank McIntoshs signature on it. Ive changed all the tubes and capacitors up to McIntosh standard. Work perfectly. No hum or hiss. Powerful 350 Watts.VERY VERY RARE in this condition. You will be satisfied.

McIntosh MI-3 Maximum Performance Indicator. McIntosh audio scope. Unit looks very nice. There is some small bubbling in the glass faceplate mainly around the edge as shown in the images. The scope has a bright display and works very well. Great for monitoring audio signal and multi-path adjustment for tunes. The unit has mostly McIntosh tubes inside which look to be original. Buyer pays $50 shipping in CONUS
