BR928 Posted March 20, 2003 Share Posted March 20, 2003 I just acquired a 4 way MCM 1900 system. Can you tell me the date of manufacture? The serial numbers are as follows: MWM S 1001,1002,1003,1004 MSSM 1137,1138 MSM 1137,1138 (Optional Gauss HF-4000 Driver) MTM 1411,1412 CROSSOVER 1003,1004 The date on a woofer I checked was 67-8607. Figure that is 1986. Have the MCM's always used piezoelectric tweeters? The tweeter arrays were disassembled and one of the 8MFD caps has been changed. Are all of the tweeters paralleled? The barrier strip only has a spot to terminate 4 tweeters. (i.e. 8 point terminal strip) Do I assume you just double up on one them? Is a replacement 8 MFD 100V oil filled cap available? Thanks for your help. Stan Quote Link to comment Share on other sites More sharing options...
khorn58 Posted April 10, 2003 Share Posted April 10, 2003 I am preety sure they used the EV t35 tweeter when new. They probly changed the twetters out when the got the price o to replace the EV tweeters. You could look under the klipsch 2 channel forum and look up Hornbuilder he use to build the old k;ipsch back in the eights I think. Quote Link to comment Share on other sites More sharing options...
