Aleph J-X pcb group buy, 3rd run - Page 5

KatieandDad · 27th January 2012, 04:35 PM

I do feel the DIY bug biting again.

I've already built a beautiful Aleph 4 and I was drawn to the higher power version of the Aleph J-X.

I'm looking at about 100 W / Channel as my speakers (B&W 683s) are not efficient and are power hungry.

The Aleph J-X maintains the qualities of the Aleph 4 and combines them with the qualities of the Aleph X.

Question is - Which boards are best ?

The AJ-X amp board has 2 scoring lines and is good for two channels of a regular Aleph J circuit or one AJ-X channel.

Price for two channels pcb is USD$22, paypal payment to my e-mail address posted here: DIY Chip Amplifier Kits, PCB's, Components and Information.

A matching PS board is also available at USD$22 and it's good for symmetrical supply in a stereo setup. If you want dual mono, you will need 2 PS boards: Universal Power Supply PCB

Prices include shipping, all boards will be shipped by airmail, with no tracking and no insurance and I cannot assume responsibility for lost packages. If you need insurance, please add $7 to your order.

The boards will be available early next week.

Hello,
Did you still have PCB's available? I plan to build 3 amplifiers and I am looking for the necessary PCB's. Thanks

A few questions.

Are these on the same spacing for the output devices as you F4 boards?

Can the gain be lowered (is there a schematic somewhere?)

Peter Daniel · 21st February 2012, 03:01 AM

This is exactly the same spacing as with F4 boards, not sure about the gain, but most likely it can be lowered.

I am interested for dual mono. How much should I send? 44?

badrisuper · 13th April 2012, 06:16 PM

Thanks
