mike tarelli Posted April 30, 2012 Report Share Posted April 30, 2012 Finally managed to find a pair of LSTs. A 700 mile round drive bought me front wired original units,good cabinets,labels in place,boxes and literature.Serial numbers HL 2779 and HL 2780.Original owner.I re-foamed the woofers,polished the front plates and I thought all I had to do was order some linen from 123 stitch.However there is a nasty "rasping" sound from the tweeter in one cabinet and the same from a mid in the other. Not there all the time but very apparent on something like piano or flute.I noticed the tweeter first and had a look on Vintage AR. There are the HI-Vi units listed but also something different (and new to me) for the LST.Does anyone know anything about them? Surely the tweeters are the same as the AR3a. It also suggests only fitting one unit.The serial numbers are HL 2779 and HL 2780.Oh yes both fuses were blown.I would appreciate some suggestions and advice on how to proceed. I am in the U.K.Thanks,Mike. Link to comment Share on other sites More sharing options...
