If anyone has interest - The AR3a "improved" crossover works.
Please find the schematic and pictures of the finished result at :
www.diagrammer.hobbysider.dk and the AR3a "button".
The AR3a "improved" is ready for playing and sounds great - best with only the specified 1 Ohm serial resistor for the midrange and no reduction of the tweeter signal. Very open sound together with expanded stereo perspective and the well known AR woofer attack.

Very cool! Thanks for posting that.
I didn't see a schema for the x-over - should I?
(it's working for me, Dave).

Non payment sites?
Hi,
In Europe we have had very slow internet connections lately, and may be the free non payment sites in DK has some affect as well. You may have to try later.

Giving this thread a bump as #2 son returned the AR3a's he had in his living room for the past 5 years. He did the L-Pad replacement, new woofer gaskets etc. (He's moving to Pittsburgh from NJ). One of his kids put a nice hole in the grill cloth, otherwise they're in good shape.
I bought these in NYC in the mid-1970's. A workmate had a pair as well, had purchased a Pioneer "Super Tweeter" to help them out.
The XO design presented here might solve some of that issue. In the interim here are impedance charts for the 3 components:

Yupp. why not? They only have numismatic value if they sit out in the library and don't get played.
Will be intersting tp document/
I've lost the correspondence between me and AR back in the late 1970's -- these were powered with a Pioneer SX-838 and sounded pretty good, but a bunch of kids came along...
