Newbie AR3a restoration: best way to refoam for beginners?

[Lilscamp]

Posted a thread a couple of days ago about wanting to get my AR3a’s restored professionally, but after thinking about it and with some encouragement, I have decided to try my hand at restoring them myself

The woofers definitely need refoaming, and I bought some replacement foam from Rick Cobb, but I guess I didn’t realize these didn’t come with shims or a dust cap. My question is which refoam method would be best for a beginner and have a larger margin for error? I like the idea of avoiding cutting the dust caps with the test tone method, but have read the shim method would be the only way to inspect the voice coils?

Hopefully @GD70 stops by and shares his vast knowledge regarding speaker restoration.

Actually disregard previous post, I see he has already offered assistance in your other thread started this past Monday.

If it were me I would follow up there instead of this new thread as you already have a good starting point. I see your relatively new here so no need to have multiple threads on the same topic

Hello Lilscamp!
You have a great set of iconic vintage speakers, one of the best!
I think you can do this work yourself. There’s dozens of threads here and on the web showing the process. There’s also many how to solder videos on YouTube, it’s very easy to do.
First, you’ll save a lot of money doing it yourself, second, you will learn a lot about your 3as, third, you’ll gain great satisfaction completing the restoration.
Google “The AR3a Restoration Guide”. It’s on the classicspeakerpages.net. All the info you’ll need is there.
I’ve restored many sets of 3as. Here’s a link to one of the...
