    This thread will contain posts and links related to technology used in Mc gear. For example, technical explanations of autoformers, unity coupling, etc.

    It's not a place for debate on the technology, rather, it's a reference area, so please keep all posts on point.

    Thanks!

    Yes..... thanks for posting. Now that I've read, do recall reading before at some point in the distant past.

    Turntable stuff in a McIntosh forum????

    Those of you who might have attended a Gordon Gow seminar probably remember his emphasis on turntable setup and calibration. McIntosh imported customised Wild microscopes for their dealers which some cartridge makers copied. I pulled my Wild out of storage today to see if it will help me with LSI solder job tomorrow and while cleaning it up I thought I would see if I could get some pictures thru it to my little Canon without a lens mount. I hope I can detail this out for a future post archiving what Dirk Roos (McIntosh Vice-president for Dealer Relations) taught me about measuring stylus wear back in 1979.

    I tried to include a mailer that we sent out in 1980 but it would not allow me because I already posted it under Shure stylus microscope over in the TT forum. Many of you might have received a similar mailer from your dealer back in the day.

    I am curious how well the two styli pics come out. Please let me know how well they come out on your monitors. The second, the darkest, is the most important as it shows the actual contact surfaces with minimal scatter from internal reflections and would be at the light level used to measure at the + or - 25 degree marks.

    McIntosh speaker white paper The last page- speaker pictures.

    Also the second download is the speaker charting paper. Somewhere I have notebooks with hundreds of these from years of testing speakers in customers homes.

    MQ107 and customer preference

    I have attached pages 2 and 3 of the MQ107 owners manual highlighting McIntosh's position in th 80s on room voicing and the feedback we as dealers reported back to them from our customers.

    Dr. Floyld Toole wrote a series of white papers on loudspeakers that are actually quite good. The one article that really struck home is one titled "Maximizing Loudspeaker Performance In Rooms" It was his description of a Karlson cabinet that really made sense. My father build two of the Karlsons for 15" woofers. After he died I dismantled and tossed those cabinets into a dumpster which is where they should have been in the first place.

    I actually did some of my own measurements and calculations long before I had heard of Dr. Toole. These measurements were to determine what sort of driver would actually work well in a Karlson. The resultant data described a driver that could not exist. It was akin to making a box that was bigger on the inside than it was on the outside.

    Look up the Floyd Tool white papers. They are a good read. In all respects they agree with the McIntosh white papers.

    Wow . . . I had no idea that Stephen Mantz restored those amplifiers (they've been on eBay for a bit now). In my old circles, Stephen was known as one of the car amplifier gods.
