Frequently Asked Questions

I would like to etch a few boards myself. Can you send me your design files?

The board is not etchable. The design features tiny traces and vias that cannot be reproduced without high-end PCB manufacturing equipment.

How does it sound?

People rate Revision A somewhere in between Chaintech 710 and EMU 0404. While it is believed that the changes introduced in Revision B may improve the sound, the new design has not been prototyped yet and no definite answer can be given at this time.

How much does it cost to build?

PCB + all on-board parts should cost 20-30 ($36-$54) depending on the powering option and parts you choose. This excludes taxes, P&P, enclosure, and output connectors.

I have a question. How do I ask?

If you have a question, please post it in the design thread. You may need to register first.

I want to contact you directly. How do I do it?

Please note that all support questions should be posted in the design thread. If you have other queries, send me an email at
