jgscott Posted February 13, 2012 Report Share Posted February 13, 2012 Hi,I am in the process of restoring a set of AR12 speakers. I have run into a problem that one of the tweeters is not working at all. The Markings # are 1200011-2.A few questions ?1.Does anyone have one they want to sell that works as designed no problems ?2. Does anyone know where I can find 1 to buy ?3. Does anyone know off a place that is good with, and may possibly be able to fix it?Thanks Link to comment Share on other sites More sharing options...
KlausDK Posted February 14, 2012 Report Share Posted February 14, 2012 HiWhat you got is the 8 ohm version of the AR-10Pi/AR-11 tweeter. Not so many of them around, but ebay.com might (again) be your best source for a spare driver. I have seen an original replacement unit, which was an 4 Ohm unit (1200011-1) with a resistor connected to one pole and glued to the back (2.7 Ohm as har as I remember). This will maybe reduce the output somewhat, but solve the impedans issue.I have had two 1200011-1 sucessfully repaired by this man: www.sinevoice.com located in Belgrade Yougoslavia; not an easy solution.BRgds Klaus Link to comment Share on other sites More sharing options...
jgscott Posted February 17, 2012 Author Report Share Posted February 17, 2012 Thanks but does anyone know anybody in the USA who might repair that tweeter ? Link to comment Share on other sites More sharing options...
flg Posted February 17, 2012 Report Share Posted February 17, 2012 Try to send it to Larry of Vintage AR, he fixed a 3a Improved tweeter (same as late 3a) for me. If it’s a broken lead underneath the plastic taped front, you may even be able to do it yourself.Fixing the original tweeters is the right approach, as anything else, other than an identical model replacement, will be a compromise.FranciscoP.S. Correction: after looking at a picture of your tweeter I don’t think you have the plastic taped front, so the internal wiring may not be accessible at all. I’m no expert, so I’ll let someone else give their judgment. Link to comment Share on other sites More sharing options...
jgscott Posted February 19, 2012 Author Report Share Posted February 19, 2012 Yes it is the plastic tape front tweeter. Thanks I have talked to him before. Correct if is is the wire then yes but I don't think it is. I pulled that off, but it did not look like that was the problem. Link to comment Share on other sites More sharing options...
