mike tarelli Posted July 5, 2009 Report Share Posted July 5, 2009 Hello from the UK. Hope this works as it is my first post. Recently aquired very battered pair of European version AR6 with 3-way switch. From the date on the tweeters they must be from 1974. One has serial number 010084. The other number is missing but very similar. However the bass units have been replaced with AR units 2000370 5618142 which dates them as 1981. As I hope to re-foam these and have the cabinets re-veneered, my question is this. Why do these bass units have a capacitor and a resistor wired in parallel across the terminals and do I leave them there? Hope this is not a silly question. Thank-you,Mike.

Thank-you,Couldn't say why they are there compared to earlier AR-6's that don't have them, but the schematics we've seen of the units with 3-position switch indicate that they are original. I'd leave them there. Link to comment Share on other sites More sharing options...

Thank-you,Mike.Hi MikeLook in this thread, there has been a total of three different cross-over designs in the AR-6, the three way switch was one of them:http://www.classicspeakerpages.net/IP.Boar...?showtopic=1687BRgds Klaus Link to comment Share on other sites More sharing options...

My problem with a search is that the older topics only display the original text and nothing else. I have to rely on the "final post "when what I need are the posts between them. It could very well reflect my computer skills!However it appears that the 3-way switch would effect the woofer without the capacitor and resistor.Thanks again.Mike Link to comment Share on other sites More sharing options...
