Nice - look forward to seeing the completed amp and test results.

Are you planning a group buy or selling the boards later on?

Thank exactly feedback.

Regrads,
and from where are you gonna get the power to let the amp deliver that amount of power?
direct from the power plant? a 230V/16A or 115V/20A line is not gonna do the job. so what the heck is the point?
