Some more pix... Just brief Description, This is a regulated version gainclone with a supply of around +-28v, I used Peter Daniel's pcb's, with the Zobel network connected and ci used. Its connected to a DIY speaker as well, a backloaded horn using Fostex FE126en. This is my first DIY projects and I'm loving it...The sound? well.. its fantastic!!

Did you soldered the resistors to the stepped attenuator by yourself?

reytnz · 6th September 2010, 10:48 PM

Yup, I've just followed the instructions that comes with it. I lay all the resistors on a piece of paper and label each value making sure I've got the right one to go to the right sw. terminal. I made sure I've got it in one go, without overcooking the contacts.

I see many exposed conductive parts.
How have you connected them to the Safety Earth, when there is no enclosing metal chassis?

Wow! mind to share some more? Do you use one ground plane for the whole system? Grounding such a multichannel PCB can be a challenge and we can all learn from your information, so please share..

With kind regards,
Bas
