Here's the schedule:

- GB closes Sunday September 25th (this Sunday)
- Place PCB order Monday September 26th
- Boards arrive two weeks later on Monday October 10th
- One week to assemble and test all variations brings us to October 21st
- Payments will start to be accepted October 21st and boards/kits will ship out the following week.

I hope that clarifies things!

Hello, I'm curious about the design techniques used to design the PCB.

Is the PCB designed with a center ground plane or a star ground?

what is the power/signal/plan distribution like?


EDIT: Also if this is not asking too much, can someone show me the square wave response of the amplifier?

An image of the layout would be nice too.



According to your schedule PCBs are now in production - could you please the finally specify board dimensions (with mounting holes location) and layout please?

Anticipation iz makin'me . . . Short of working on a case there is little to do to cut the anxiety called forth by anticipation so, Jacek, if you need to build it now, just build it BIG :-)

I am eager to build it too. Everything iz procured, powsupp iz ready, so I lashed up a way to A-B compare the bal-bal to a pair of bridged LME49600 boards, each using a pair on the push and a pair on the pull. Thinking about test now iz a good way to get ready even if you expect, as I do, the null outcome. Also take the time to think thru the cabling now to avoid the last minute rush to that 'first listen'. When I first connected the bridging noted above I used blocking caps that, upon reflection, were not needed and misled me to an unwarranted disappointment.

The layout has already been posted (the se-se version anyways) in post #658.

No space for a pot it would seem.

Unless you are referring to something else?
