M-Audio convertion from grounded bridge to class H.
This amp started before pandemic.. The first plan was to repair and just be done with it, it comes to the point that it is too annoying to maintain and not to mention costly if you like to replace all the driver boards. Then I suggested to replaced it with diy grounded bridge designs but the problem was the driver board I used way back was EV and it needs to have high rails supply to run. So, I decided to design the pcb layout of qsc inspired amplifier which is not very common at that time and I havent run it on high rails.. blah blah blah this happen.
Imagine how long it is to make... from redesigning to making diy prototypes, then finally implementation of prototypes factory made pcb.
