JKent Posted July 20, 2007 Report Share Posted July 20, 2007 Hi VernJust bought a pair of these and have been searching for info. You have provided some good lit and pics, but I was frustrated that a page of the review was missing. Do you still have it?attachment 3 is MicroStatic20016.jpg (p 34 of the review. Says "continued on p 45")attachment 4 is MicroStatic40019.jpg (page 46)Do you have p45? Any other Microstatic info would be appreciated.btw, I also read the other thread. Interesting stuffhttp://www.classicspeakerpages.net/dc/dcbo...g_id=217&page=2I'm attaching the pic from the ebay listing. Pretty fuzzy. Any other info you may have would be appreciated (even the basics like how to hook them up or how to take them apart)Thanks VernKent Link to comment Share on other sites More sharing options...
dynaco_dan Posted July 20, 2007 Author Report Share Posted July 20, 2007 Hi there;I have nothing else to post here regarding these speakers. Link to comment Share on other sites More sharing options...
JKent Posted July 20, 2007 Report Share Posted July 20, 2007 Too bad. Don't know what happened to p 45 of that Stereo Review article--it's the flip side of p 46. which IS posted. Anyone else happen to have it?Also interested in repair info. I bought these as a "second chance" offer, some time after they originally sold, so I'm guessing they may not be working properly. Could be a fun project. Link to comment Share on other sites More sharing options...
JKent Posted July 21, 2007 Report Share Posted July 21, 2007 Found this interesting page for Roger Russell, apparently the designer of the McIntosh speakers (funny you don't hear much about Mac speakers). He had earlier worked for Sonotone and was responsible for their switch from vented designs to acoustic suspension designs. He’s written a history of Micro/Acoustics here:http://www.roger-russell.com/sonopg/micropg.htmHe has a wide range of interests and accomplishments. Check out the link to NoTone Audio! Also links to info on Scripto pencils, lightning, “mystery clocks”, high-priced speaker wire, column speakers, sci-fi, etc. etc. etc……..http://www.roger-russell.com/#otherpagesHe will also sell copies of that SR review, so if no one posts the missing page here I may buy it.

JKent Posted July 24, 2007 Report Share Posted July 24, 2007 Well, they came today but the sound is VERY faint. I do get sound from each of the 4 drivers in each enclosure. Thought I'd replace the caps, maybe even the pots and slide switches.Mine have the "nonremovable" backs but I removed them. Funny thing is, just like Vern's, the slide switch only uses 2 of the 3 lugs and the pot only uses 2 of 3 also. The attached pic is one of Vern's but mine look the same inside (except the caps are physically much smaller)Any ideas? Anyone have a schematic? If the tweeters all produce "some" sound, what's the likely culprit? Does it make sense to replace the pots and sliders, or just the caps?Sorry to be so ignorant...........Thanks for any helpKent Link to comment Share on other sites More sharing options...

dynaco_dan Posted July 25, 2007 Author Report Share Posted July 25, 2007 Hi again;Time expired on me again.I have not seen a schematic of these yet.How did you remove the non-removeable rear cover? Link to comment Share on other sites More sharing options...

dynaco_dan Posted July 25, 2007 Author Report Share Posted July 25, 2007 Hi there;I guess they were looking for a cost cutting measure.They certainly found it.Not as nasty to service as the earliest KLH speakers at least.Thank you for that photo.

JKent Posted July 25, 2007 Report Share Posted July 25, 2007 There must have been 2 versions of the Microstatic tweeter. According to the Stereo Review article, it has 2 1 ¾” drivers and 2 1 /2” drivers. And it measures 9 1/8 x 5 ¼ x 3 ¾. This is consistent with the “Technical Specifications” provided by Vern. Neither Stereo Review nor the TechSpec gives model number, and the second page of the review is missing. I have a friend who said his are Model FRM-1 and they have 2 level controls.Mine have only 1 level control, like Vern’s photos. According to Roger Russell’s web page, the tweeter is Model MS-1, has 4 1 ¼” tweeters and measures 4x9x5. That description is consistent with my tweeters—they appear to have 4 drivers of equal size, and the measurements are 4x9x5. They also appear to be solid walnut –not veneer.A few squirts of cleaner/lube to the L-Pads and slide switches seems to have got them working and they sound good, but I’m still going to recap them. Each crossover has two 1uF 50v NP caps. I may leave the 25 ohm L-Pads alone. Link to comment Share on other sites More sharing options...

JKent Posted August 9, 2007 Report Share Posted August 9, 2007 I see there is a fellow on the For Sale section selling Matsushita replacements for the Peerless tweets used in Mac speakers. According to Roger Russell, these are the same tweets used in the MicroStatics, so I guess those Matsushita replacements would work in the MicroStatics.Fortunately I don't need them. Mine sound good with the new caps and cleaned up switches. They are a nice addition to my KLH Twelves. Just sorry I missed out on the pair just sold on ebay (by $1)Here is one tweeter's innerds with new Dayton caps, and a shot of it atop the 12.
