One more picture to add today. My dual mono conventional configuration of the ACA Mini design is now alive, biased, stable and sounds great!Believe it or not, this is actually an ACA Mini but I took the liberty of laying out my own boards so I could create a more conventional implementation with a more standard chassis. I just finished the assembly. One board has been brought up and tested and all connections have been checked. So all looks good but I won't have time to bring up and bias the finished amp until tomorrow. I'll post a picture with lights on once that is done.
