Default Newbie Questions About Aleph J

I'd like to build an Aleph J.

When I search to find an amp schematic, PS schematic, and BOM, I get so many hits it's overwhelming.

Can someone point me in the right direction?

Thanks

Mike T.

There are boards for pre-order in the DIY Audio store for the amp. With a build guide to come. The thread about this is the one about Aleph J for the universal mounting system they are using at the DIY Audio Store.

Aleph J for Universal Mounting Spec

I plan to work this further after I build the ACA from the kit.

Mike - Yes, the link Bones provided is all that there is, for the moment. There will be a build guide before the end of summer.

Default 2SJ74?

Thanks for the info. I found the BOM and schematic.

Also, I apologize for not remembering my previous post. I am old, and I have slept since then. These days I make new friends every day and I can hide my own Easter eggs.

Question: Is there any current production substitute for the 2SJ74. I'm sure this is not an original question.......

Mike - No, there isn't. There are still a couple good options, Check your PM and we can discuss good options.

No apology needed. Building these amps is an Easter egg hunt while riding a bull in the middle of the jungle.

The boards have gotten to the warehouse, and my JFets are on the way from Hong Kong (thanks Spencer). Hopefully those are the hard parts, I will be collecting the rest of it slower, as my Aleph J build is after a couple of other projects.
