I don't think so but it appeared in Sound Practices 30 issue #13
which can be backordered :

SP

You're quite right...It's been like this for a few years already.

I did find an e-mail address on the Altec pages but haven't tried it yet.

SP INFO???

Cheers,

Thanks for the replies. Yes I went to the SP website and it appears to be no more. I was hoping the original would be online someplace.

I might still have that SP issue - if you're really desperate

Otoh, what's the big deal with this design? It espouses the 'vintage' sound and i probably doesn't do justice to high quality sources.

Joe let his domain expire and someone scooped it up... his new domain is MIA as well.

He still has back issues (you have to buy them as a set -- and it is not complete), but it is best to get the CD. Joe can be reached at jroberts -at- io.com

i have the original schematic which i also scooped up many moons ago. i'd like to ask permission from the diyaudio team to post. just let me know if it's ok or not

hi analog_sa, can you kindly describe to me "vintage sound?" (sorry, i don't own any vintage equipment)

i have built a variant and it sounds great on my relatively new el cheapo Harman Kardon HD750 HDCD player (but my Oracle sounds better ) am not sure if i was hearing a vintage sound. if it does, then surely match well my my Altec on open baffles then

That is a sticky one... write to Joe & ask him if it is OK. And it would need to be accompanied by a link back to somewhere to help Joe sell SPs. If you don't want to write, i can 9but i may be a while)
