Hi all,
I bought the AN/E kit speakers probably 20-25 years ago, really enjoyed them but when I started playing about with vintage full range drivers and DIY I pulled the drivers and crossovers and junked the cabinets I'd made to save space.
A friend of mine wants to build a valve amp, so I'm helping and suggested he try my audio notes.
I plan on building them into AN/J so if he doesn't go for them they will be small enough for me to use as a second system.
I've replaced the foam surrounds that had both disintegrated.
Only problem is I've lost the build plans. I know the outside dimensions and can experiment re port length but wondered if anyone can help on details,
is the baffle double layer?
What thickness is the ply?
I remember a brace under the midbass, what dimensions is it?
Any help much appreciated.
For context the amplifier is being bread boarded to work with a variety of tubes I have in stock so my friend can see what he prefers. 6cb5a, 300b sv811-10a and a variety of other sweep tubes, setup can use D3a, ef180 ef184 6j9 etc as drivers via power drive, Should be fun to rattling through the permutations!
Many thanks
Enzo

Pretty sure the AN/J is a much smaller speaker, with a different woofer? So the original AN/E plans would be useless anyway. If you have access to your original woofer T/S values, that would make designing a new box fairly straight forward, otherwise you'd need to use old school math.

Mattstat, that looks very close, are these plans Snell e? Dimensions look slightly different but design looks the same 👍
Vinylekid I believe the j is an e missing the bottom 8-10 inches, same drivers, probably the same crossover just tuned to ~26hz rather than 17 (at a n idiosyncratic -6db)
When I had them in an e enclosure the bass would overpower my 8 X 4m room, I'd guess bad dimensions for modes, so I'll be happy with j's. Could always use my 15" bass speakers to sure up the bass.
Hopefully my friend will like them.

The image name on the post by @planet10 says "audionote-e", but beyond that I'm not sure. He may chime in to help clarify. I think there have been several revisions to the design, but I'm not sure if those were basically just driver and crossover changes. I think the port moved from front to back along the way also.
Some history about the Snell/Audio Note relationships:
https://www.stereophile.com/standloudspeakers/506an/index.html
"Audio Note's involvement in the loudspeaker world dates to the early 1980s, when audio maven Peter Qvortrup represented the Snell Acoustics line throughout Europe. Qvortrup admired Peter Snell's design innovations—not only were their cabinets precisely sized and shaped to support a particular range of frequencies, but Snell Acoustics was among the first companies to hand-match every crossover component to its own unique set of drivers. As Snell's distributor, Qvortrup enjoyed particular success with three relatively efficient models: the Snell Type J, Type K, and Type E.
Everything went swimmingly until fall 1984, when Peter Snell dropped dead on the factory floor—and his surviving business partners hired Canadian designer Kevin Voecks, late of Mirage, to take his place. Almost immediately, Voecks began to take Snell's product line in a direction that had nothing whatsoever to do with Peter Snell's original work, as far as Peter Qvortrup was concerned. I agree.
That left Qvortrup—who would soon team up with Hiroyasu Kondo to sell products under the Audio Note name—in a bit of a jam. He bought up all the remaining stock of Snell Js, Ks, and Es, and when they were gone, he bought the remaining unfilled cabinets, too. After that, Qvortrup took the only route left: He sought and obtained permission to continue building Js, Ks, and Es on his own, crediting the original designs to Snell and selling the finished products under his own label."

It is the box Chris built for a client with an AN kit. He m as midTweeter (a TB872eN for starters because they were kicking around.
If it says AN-E thaty is what it is.
Not impressed with the factory builds i have heard.

So you are correct regarding the woofer. The original Snell J/III used the Vifa M21WN-07. Do your woofers still have a sticker on them. I can't find a spec sheet for the Vifa woofers, so I used the T/S numbers from the AN/E page that Dave linked, as it's a 4 ohm woofer, and we are assuming the QTS & Vas are at least similar. I did a quick sim using the extrapolated numbers from the box dims etc. Vent is 2" dia. x 5" long.

I have the early standard paper drivers, they just say made in Norway.
I was sure they were named on Troel's site but couldn't see anything after a quick look.
If my memory is right the port in the kit was just gutter down pipe, which here is I think 68mm. But could be 2", was many years ago when I made them.
