Also here is a pic of my KLH Fives and they are walnut. They look totally different than the light color of these AR 2A's.

Congratulations on your find. This pair looks to be in great shape.
I'm placing my vote for lacquered walnut as the finish. While I wouldn't rule out cherry, the picture of the short sides of the cabinets that you show in your original post certainly looks like walnut grain.
I'm including a picture of an AR-2a I own in lacquered walnut, which looks very similar. I'm also including a picture of an AR-1W lacquered birch cabinet for comparison.
I find that I prefer the look of the lacquered walnut cabinets, what AR termed "Standard Walnut". You may want to consider simply applying a couple of coats of Johnson's Paste Wax to bring the sheen back and protect the finish.
I don't think it is walnut. I have several pieces of walnut on hand and the grain of them is just not right. Here is a pic of one of my large walnut boards (Going to make a gun stock)

So is this something you guys have seen before in AR cabinets? Definitely looks solid. Here is a couple more pics. One shows what looks to me to me a small knot in the wood and the other shows where someone stamped a number 3 in the solid panel. Of course the back is plywood.

When you get time, would you please post images of the miter joints on the rear of your cabs, using the same quality as the as the first of your images in the post above?
Thanks

Here they are. Still looks like a solid board that has been veneered to me. I even wet the jointed area to show the grain a little better.
-
Another question? It looks like my cabinets on these where made with solid wood that was veneered. It does not look like plywood. Did they make these using solid wood of some type and then veneer it? The first pic is one of mine and the second pic I pulled off ebay. You can see a definite deference.

Birch? They look great.
Very nice info. Thanks.

What kind if wood do you guys think is on these? Here is a couple close up's.

Good-looking speakers, with a desirable woofer, and reliable oil capacitors - congratulations!
You've had some excellent pointers, and I might add to use caution when handling & re-installing the midrange module. The paper cones are usually rather dry, and easily damaged. Best not to touch the cones directly. Also, the plastic enclosure has become more brittle with age, so be sure to do a good re-seal, and don't torque the screws down too much where the flange could deform, or fracture.
Good luck!
Actually the midranges are in pretty nice shape. They feel pretty good, the baskets are not brittle at all. I already knew about these problems because of my AR 2's. The mids on these are in MUCH better condition.

I found the easiest way to remove the woofers in AR speakers is to remove all the sealer putty around the basket edges and cab gap. Then you can get a wide blade screw driver under the basket edge and start prying it upward. Use a putty knife between the baffle and screw driver to protect the baffle from the screw driver as you pry the woofer loose. Once you break that seal, it will lift out easily. Notice that greenish color on the magnet? Don't touch it, or breath any dust from it. I would wipe it with wet paper towels before removing it from the cabinet.

I will try that. I will not touch the corrosion on the speakers and clean them real good. Thanks!
-
Thanks for the great advise. I plan to leave the tweeters in. I will try the paint can opener thing and see. I tried pushing from the inside with no result, that is why I remove the mids. When pushing from the inside I got scared I was going to damage something so I stopped. Well I will give it another go.

Were the grills still stapled on? Great job removing them, not a easy task. It looks like you removed the dual midranges first to get access inside the cabinets. Was there rock wool or fiberglass acoustic stuffing inside? Those oil filled capacitors may be still in speck. I know it is a lot of questions, but I really like 2A's owning several pair. One pair in original shipping boxes with serial numbers 551 and 552. One last thought, be careful with those original grills, that cloth is unobtainable.
Yes the original insulation was in there. Yes the staples on the front where a bit of a pain. I removed the mids because I couldn't get the woofer out (It is really stuck in there with that black goop). Any advise on how to get the woofer out would be great. I have never heard these before but if they are anything like my KLH 5's I know I will love them.
-
Well the grill on one came off real easy! It looks like they where made in 1962 from what I can see on the back of the tweeter.
-
The serial numbers are close. D 2140 and D 2158.

Hey Don, those 2a's look pretty nice, but I would suspect they need a full disassembly and careful rebuild with all components checked out and confirmed. After you've given them a test drive, let us know what you're observing regarding functionality of drivers, etc.
Nice to see the original grille cloth and badges - - with slow and careful attention, you might be able to get those grilles looking real good, despite the one small tear that might be re-stitched. From the rear close-up, those pots appear very crunchy - - you may want to give them a little spray of electronic cleaner/lube before you even try to give them a rotation.
Am not certain, but I think you may have birch cabinets that have a light brown or honey stain by previous owner? Just a guess, but it does not look enough like cherry or walnut.
Yes the pots look pretty bad. I agree that they will need refurbished. The original owner had these placed inside a cabinet so they didn't get to bad as far as the finish goes. All I know is I can't wait to here them in good working condition! Pics are of how he used them,

I think I might call these my Crona speakers. I think the reason I got them is the fear of the virus kept everyone away from the estate sale these where at. I showed up late and they where still there with a $50 price tag on them! I have not hooked them up to anything yet but I plan to check them out good before I do.

I would love to see pictures. Nice find.

Exactly this, DonT thanks to the detailed photos, among my projects there is really a replica of AR-ST and I think that the scheme is the best help to be able to reconstruct this speaker.
Sincerely, thank you for your kind reply !!You are welcome. I am glad it well help. I do have an original 3st I need to replace the capacitor in (Just have not got to it) When I do I can post pics of the inside also.

All wonderful, but can you publish complete photos (if there are 2 pages, both) of AR-3st Wiring Instruction?
You can see the complete wiring diagram (including coil, resistor and connections) that I and many fans need and you could use it for reconstruction of super tweeter units!Giorgio
If this is what you are talking about here are some better pics. It is only one sided. I can scan it and email it if needed, That might be better?
-
I am sure you guys have seen this stuff before but I thought I would share. I was going through some old paper work and look what I found. Some original AR paper work. This stuff came with my AR2 and 3st that I still have. I didn't realize I had duplicates. Cool info in these.

Masonite ring woofers have inverted roll surrounds, all of them, or SHOULD have. The later all-metal woofers have standard mount with the roll poking out, or SHOULD have. The only way they get switched is if a subsequent owner changes them or a "professional" changes them.
Doug
I hope no one is confused about mine because I installed them just like you said Doug. They are inverted. If it looks different to anyone it must be an optical illusion of my picture. Oh and I have been listening to these stacked on my KLH Fives and I LOVE them like that. It just sounds great! I think I might still keep my eye out for another pair of Fives though ?

Speaking of keeping these as close to the original as possible, It is interesting to note that the original Advent woofer has inverted foam roll as in this instruction video.
That is exactly how I did mine. If it looks different to you it is just the pic.

I got the new caps in and WOW it made a huge difference! Now they sound like something Henry Kloss made. Still not quite as good as the KLH Fives but real close. All I can say is I LOVE yard sales! So far I have got the KLH Fives for $10.00 and now these for $5.00. After rebuilding both pairs I have about $130.00 in 2 pair of great speakers!

Cool. And looking at the wood it also looks to be sold to. I wonder if they did that a lot on earlier models?
