Interest for XEN Headphone Amplifier Motherboard

Status
This old topic is closed. If you want to reopen this topic, contact a moderator using the "Report Post" button.
Following the initiative by Algar_emi of a motherboard for our HPA projects, there are request for our "original".
You can enter your interet for the mother board alone here.

It shall follow the new layout posted in the current drive thread :
https://www.diyaudio.com/forums/hea...-super-linear-transconductance-amplifier.html

and include on-board through-hole passive crossfeed.
The volume pot is placed recessed, close to the crossfeed and amplifier inputs for shortest path.
It will thus require a shaft extension to the front panel.
Small price to pay for optimal layout.
SHPP will not be included, as there are different types.
But we'll most probably include AUX PSU for SHPP:

Price not know yet, but most likely not be less than 500 HKD.
This is because of high postage costs due to the size of the PCB.
Also it will be 2mm thick, and include all the cutouts (not the case from Algar).

Please enter your interest below in a running list.


Many thanks for your interest,
Patrick
 
I have looked at the other threads and want to make sure I understand what will be needed to complete this headphone amp.
From the photos it appears the board includes individual power supplies. Are the smaller daughter boards included or is this another GB? Also I would be interested in the SHPP if available.
Tnx
David
 
All the other daughter boards are included in the amplifier GBs.
The motherboard has integrated Crossfeed (not extra board) and separate PSU for SHPP.

For extra SHPPs pls contact dabore84 first.
If he runs out then perhaps start a new GB thread for SHPP only and see how much interest there are.
See details from :
GB XEN SHPP (Simple Headphone Protection)


Thank you for your interest,
Patrick
 
The latest update with two aux PSU added for, e.g. SHPP.
