    Mi querido amigo: magnífico vídeo, ya estoy deseando poder ver la segunda parte del mismo. Por favor, no tarde mucho en subirlo a su canal. Por otro lado, me llama poderosamente la atención el tremendo cortocircuito que se ha producido en las dos etapas de potencia, ¿cual habrá sido su avería?. Lo dicho, muchísimas gracias por sus aportaciones, un gran abrazo desde Las Islas Afortunadas (Islas Canarias - España).

    PCB damaged badly. Copper traces vaporized and resin carbonized. It is better to change with new whole modules.

    Base on my experience of repairing power amps i suggest to fixed the differincial voltage.. make it steady voltage even sounds gain up level.both differincial voltage and power output voltage steady ...when voltage low then up while amps is working..im sure parts is burning again and again..cause headache wasting money..

    With 3pairs of 1943/5200 I wouldn't ask for more than 150-200W@8 ohm, and keep lower rail supply for 4ohms. Weird it took 0.22 resistors, wow lots of current. Maybe there is problem with oscillations in power output section.
