Aleph J for Universal Mounting Spec

[RainfallSky]

This is how it could have looked with LEDs intstead of Zener.
Or should i beter go with a string of five for 9V?

I think I will consider my DIY Aleph J layout as complete and move on.
Although it was never beta tested..

Now I want to try to make Aleph J-X layout.
Plan is it would also be UMS heatsink compatible, as one solid board per channel, with 8 pcs of IRFP240 per board.

As I understand Aleph J is single ended and Aleph J-X is push pull.
I wonder how they sound in comparison.

I notice the links to the BOM are all dead (click and nothing happens). Are these available?

Hey Everyone - Im using the Blogspot build guide. R1 for the amp boards shows up twice in the saved Mouser cart. The values are different.

https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=35ACFA214D

Is that just an error? Which of the two should I use?

 

[btol]

Apologies. Realized I posted in the wrong thread. Mods please delete.

Extremely late to this party...but a friend told me to build myself one of these. So I was wondering will the FET part kit ever be available again? I see the boards are available.

little birdie told me - soon

Thanks...I did not want to be holding some un stuffable boards

Have anyone tried to use the Linear Systems LSJ689 dual p channel to replace the hard to find LSJ74s

I would greatly appreciate the input/tips from one who built the Alef J using LSJ689.
thank you

Where are you going to get the LSJ689?

I hope its a legit place

 

[Zen Mod]

dunno

looking at Linear Systems web page is certainly going to help

 

[Eitan100]

According to the list, they are listed as a legit distributor in the US.

When you actually have them in hand, we will be more than happy to help.

In the time being, you need the J74 quad 8-11mA. https://diyaudiostore.com/collections/frontpage/products/matched-jfets?variant=39335246987337

Hello, super new here. I just recently built an ACA and a Nutube preamp and I'm absolutely hooked. I'd had some minor problems, looked up some past comments on the threads, and sure enough, just needed to do some re-soldering and things were great. I'd love to take on another project, it seems like the Aleph J would be amazing. The guide seems great, and most of the parts are available. I'd love to ask this forum a) is the Aleph J a good next step, and b) anyone know ballpark when the diyaudio store might get new stock in of things like the power supply boards, and the transistor kit? Months? Years?
Thank you thank you!
