donroyledbetter Posted March 13, 2003 Share Posted March 13, 2003 I posted this in the wrong forum and got a reply from the Builder. any other comment will be appreciated thank for the hours of interesting post education. i bought a pair of lascalas at an army surplus sale in '92. PLEASE HELP me with the ages of my children. LSBR serial#s 54939 and 98609, why out of sequence? K-77, one is stamped 52833 K-55v, one is stamped 54939 woofer is bottom access,have not opened yet but after reading posts i need to know if they are industrial? type AA balancing network. thanks, don HDBRbuilder Posted: 3/12/2003 10:51:31 AM HDBRbuilder No Life Total Posts: 1,836 Last Post: 3/13/2003 Member Since: 4/13/2002 Check those serial numbers again...look REAL close...also...give the names of the "tested by" and "inspected by" folks on the labels...I would imagine yours were tested by N. W. Bradford. I also would imagine that the third digits in the speaker serial numbers you gave are NOT numbers, but are instead the letter "S"...so look real close!! If, indeed those third digits are the letter "S", then the year of manufacture was 1978. "LS-BR" is not the industrial version of the LaScala...it means: La Scala, Birch, Raw(no finish). With LaScalas, there was no need to pair them up with consecutive serial numbers when selling them...and since yours are military surplus, they were probably originally bought as singles anyway. Industrial LaScalas are designated with either "LSI...": La Scala, Industrial; or "LSSI...": La Scala, Split-Industrial, followed by either a "BB" or another pair of letters designating the finish type. Since yours are NOT industrial models, they SHOULD have K-33 woofers in the bass bins, unless they were changed-out after being shipped from the factory. -----------------------------------------------------------I may be stupid, but I can lift heavy things! (And when building LaScalas pretty much with little or no help, you gets lots of chances to lift heavy things!!) -------------------1983 60th Anniversary Edition BMW R100RT------------------- donroyledbetter Posted: 3/13/2003 9:02:50 PM donroyledbetter Newbie thanks for your help, I have looked again with strong light and a magnifying glass and can add the following information from the aged papers. both stickers are printed LaScala-E. both signed tested by: N.W.Bradford ,in his scrawl, in black pen, probably ball point on fresh paper) Both are signed inspected by: J.Barker ,in his nice controled hand, in what i suspect is a fine point felt tip pen, maybe a "Flair". both are faded, one more than the other. both are type: LSBR lettered in J. Barker's handwinting. now the sticky part. both serial #s have been altered. one serial # was originally lettered in J. Barker's hand: 7B407 and crudly changed to 98609 by some one with a ballpoint. the 7s that resemble the L in LSBR but upsidedown were changed into 9s, under the 8 resembles the B or possibly the R as in Barker and LSBR. the 4 is open on the top, the 0 is a best guess. the other oridginal # is to faded to even guess. these speakers were bought at an official army surplus sale. experience with army hand receipts says that these may be one of the many #s they give every toothpick, writing over the original #s was probably logical to that sharp mind. i can't think of any other reason to alter. on another track, 2,731,101 is the latest patent # in the list. i tried to download it but could'nt open it and will try again now. these are all the clues i have come up with so far. what do you think? thanks.don Quote Link to comment Share on other sites More sharing options...
HDBRbuilder Posted March 14, 2003 Share Posted March 14, 2003 Let's presume the letter in the serial numbers was originally an "R"...that would make them 1977 manufacture...and that would coincide with the names found on the labels for the inspector and tester. Your components in these(if still original components) should be: Tweeter: K-77 (round alnico magnet) Midrange horn lens: K-400 (black-painted aluminum alloy) Midrange driver: K-55V("greyish"-painted alnico magnet) Woofer: K-33 or K-33E (either square or round ceramic ferrite mud-slurry magnet) Crossover networks: Type AA Quote Link to comment Share on other sites More sharing options...
JohnA Posted March 14, 2003 Share Posted March 14, 2003 The real serial numbers will be stamped into the edge plys of the plywood near the crossover, usually in the edge of the sheet that forms the back of the bass horn. If they have not been modified, they will be no newer than 1982. The 3rd character will be a letter and it will be an "X" or below. Quote Link to comment Share on other sites More sharing options...
donroyledbetter Posted March 16, 2003 Author Share Posted March 16, 2003 Excellent!!!! the stamped #s are 7P407 and 7P401. what year does the P conotate? don Quote Link to comment Share on other sites More sharing options...
JohnA Posted March 16, 2003 Share Posted March 16, 2003 P is 1976, the year I discovered Klipsch. Quote Link to comment Share on other sites More sharing options...
donroyledbetter Posted March 17, 2003 Author Share Posted March 17, 2003 Had to peek at my woofer. it's a K-33P. what is your oppinion of the quality of this early of a model year? how does it fit in to the milestones of klipsch history? where is a good place to find some basic reading as to what these speakers are. grazi, donaldo Quote Link to comment Share on other sites More sharing options...
