    AR-3 Restoration Complete!

    Welcome, and wow!!! Amazing job restoring those gorgeous 3's. I'm drooling with envy! They look terrific, and you even have the perfect spot for them. Congratulations!!

    Kind of weird AR 3a amp question

    Got a good deal locally and picked this up today. 200K ohm impedance. Problem solved.

    Kind of weird AR 3a amp question

    You could be right. FWIW McIntosh has informed me that output impedance for the C24 amp is 250 ohm, which makes it perfect for driving the HK22. So for the time being at least I'm going to sit tight. It sounds great with the 3a's.

    Kind of weird AR 3a amp question

    Thanks ar... Yes I have been looking for the Mac's you refer to. In fact there's one not far from me with an ask of $1100 that I might make an offer on. But paying that much(or maybe a little less) for an amp that has the same power as the HK, and is not restored, does not bring me confidence that ultimately it would be worth it, or at least that I would find it that much better sonically. After giving it some thought after posting I think I'm going to leave the HK in there. The C24 would have to have an impedance of >1000 ohm to get to the 20-1 ratio that is considered reasonanble for amp/pre matches. And given the printed impedance info of similar era Mac pre's I'm assuming it's lower. That it could be in the 100-200 ohm range that similar era Mac pre's were state at would make the HK a perfect amp for it. As I listen more to it, the bloat that I referred to really only happens on certain music. I was listenening to some of the new Dead Pacific Northwest box today and Phil's bass was huge on these speakers, but other music is much more in line with what I would expect from the 3a's.

    Kind of weird AR 3a amp question

    I presently have 2 amps that I can use with my restored 3a's: A Harman Kardon Citation 22, which is 200 watts@4 ohms, and has a high currrent mode, and a Nikko Alpha 230, which is 130 watts@ 4ohm, and is current limited. Both amps are fully restored. My dilemma is that the preamp I'm using is a restored McIntosh C24. While it's output impedance is not to be found anywhere, according to literature one should use amps that show a minimum of 47-50K ohms with it. On another forum a graph was produced using the C24's schematic which indicated that McIntosh's recommendation was correct. The HK is 22K, and the Nikko is 50K. The HK produces more bass, almost to the point of bloat on some recordings, where it would seem the loudness setting is being used even if it's not. That said, it sounds very good overall. The Nikko produces less pronounced bass, and is a little drier, so it sounds more "accurate". So I'm looking for some guidance/thoughs as to the amp that folks here would suggest using. It would be nice to find a high current amp with a higher load, but that doesn't seem to be in the cards at the moment.

    AR3 with no finish. Where to start?

    Thank you Tom for such an insightful and interesting history lesson! The OP's 3's are indeed some beautiful speakers, and even as an owner of a very nice pair or early 3a's I find myself drooling over them. Hope to find a similar pair for myself one day.

    Recomend Ar speakers to pair with fisher 400?

    2ax's should work really well. I've used both a Fisher X-100-B(pretty much the integrated version of the 400) and Fisher 500C(a little more powerful, but negligible) with them and they sounded excellent with both of them. Big full sound, no issues with lack of bottom. FWIW, those amps also did well with the 3a like KLH Model Five's, although of course the Five's are 8 ohms vs. the 4 for the 3a.

    AR3 with no finish. Where to start?

    Welcome to the forum! Those are fantastic , 1st year(I'm guessing) examples of AR 3's. And yes, there are plenty of folks who will help you get them back into tip top shape. I'm going to guess that the caps, which are most likely the oil filled variety which typically don't stray much, and unless they are leaking are usually good forever, are not the culprit of your tweeter issues. Probably corroded pots which will at the very least need removal and cleaning. Again, others with more experience than I will be along shortly to give you advice on the best methods to do that. Again, congratulations on your find. Once back in shape they will be sure to bring you hours of great listening.

    AR 11

    Thanks. I'm probably going to pass as I have a pair of KLH Five's that I love, and shortly will acqure an early pair of 3a's. So the 11's are probably not in my future, although they are nice looking and I've heard good things about them. These are in the San Francisco Bay Area where everything is more expensive.

    AR 11

    $700 locally. Is that a good price? I'm more familiar with the earlier AR's. Here's a picture of the drivers on one of them. They sellers don't know if the surrounds have been redone. Can anybody take a guess from the picture? https://sfbay.craigslist.org/eby/ele/d/vintage-ar-11-speakers/6684554818.html

    AR-2ax connecting external tweeters

    I've used the Microstatic, and also have been fortunate enough to find a pair of JansZen 1-30 external tweeters, made to be used with primarily with early AR and KLH speakers. Here's a picture of both in action with my AR 2's.

    AR-2 in Heathkit AS-2 clothing

    I'd be interested if you ever got around to updating these. My experience with my own 2's were that the caps were oil filled, which are unlikely to need changing out. Would be interested if that was what Heathkit used.

    AR-XA in box?

    After being a futzer for way too many years, I completely disagree with this statement. But if futzing is something that one enjoys then by all means do it to your heart's content.

    KLH Model Fives I got a few months ago.

    Great speakers ain't they?

    Was at Edgar Villchur's Estate Sale This Weekend

    I would say yes, there is interest.
