    Build a pr. of Frankenstein ADS

    I first heard ADS L-710's on a showroom floor in about 1976. I realized that I found the clarity and depth of sound that felt right for my ears. Shortly after that I heard them I purchased a used pr. at a much cheaper price than new ones were going for. No regrets, loved them for listening to...

    Hi-Fi speaker for a really nice Fisher 500b...

    Hey everyone! First post on AudioKarma here but I've been getting advice from the forum for years! I had previously been using a Pioneer QX-747 quad amp with a set of B&W 600 s2's & a pair of JBL LX-55's (each hooked up to its own channel since there are four). I have two Technics MK2's and I...

    AR3 grille warped

    My AR3 grilles are warped enough that the support piece in the middle is contacting the woofer and causing sound distortion with heavy bass even at lower volume. I tried some different speakers and took off the grill and it took away the “distortion” vibration. Besides just using them...

    Fear the 4ohm speakers i just brought are not a 100 percent match with my 9090db

    From the reading I've done I don't have a good feeling hooking up my recent purchase of Ar3a speakers to my 9090db .  I recently found a brand new Adcom GFA 6002 Power Amp. for sale at 300.00 dollars. Would buying the Adcom solve the problem to run the 4ohm speakers with my 9090db ? Does the...

    Recapping AR-3a and AR-2x, What capacitors to use?

    OK, very new to this, I have a pair of AR-3a speakers and a pair of AR-2x speakers. I see that both use the same big fat capacitor (see pic). Can I just replace these with regular orange Polypropylene Film Capacitors? or should I use a step up of some type? thanks

    AR3a restoration

    Hello everyone, I’m in the middle of an AR3a restoration and one the woofers has very faint sound but no visible exterior damage. I swear it was working. Is there a sure fire way to tell if I’ve blown it, which I don’t think I did. I tested it with a 9 volt and it moves. The other...

    Hi speaker experts, I am trying to restore some 1969 AR3a's. I have followed the guidance from the speaker restoration pages, re-capped the speakers, and gotten the spider's on the woofer's repaired by Larry at vintage-ar. I replaced the pots with some new ones from hifiaudio on ebay...

    Driving AR3a’s With Dynaco ST-70

    Hey. Just wanted to get some insight on driving my AR3a’s with my Dynaco ST-70. I looked up specs on AR3a’s and saw that they are rated at 4ohms, but my repair guy says he always runs them at 8ohms. Can the speakers handle an 8ohm current? Is there a benefit to using the 8ohm tap with 4ohm...

I’m going to use the ARs with a Sansui 8080. I know that the 8080 is rated for one pair of 4 ohm speakers...

    Conflicting info: Marantz 2270 and AR3A's

    New here and no expert, but I'm hoping for some advice that will help me avoid an expensive mistake. I have a Marantz 2270 that I love only a bit less than my kids, so whatever vintage speakers I choose will definitely need to pair well with it. I have a pair of Dynaco A25's, and they sound...
