    I couldn't make it work. Apparently everything's fine, 60v asymmetrical feed, ok input, speakers ok.. It keeps swaying, it works a bit and for the sound, the fan goes on (or not because when I take it out of the socket it stays on for a few seconds, so it's not sure).. Did anyone there have that problem and get it to work? Ahh in an attempt like that to tidy up, I moved that trimpot or that train that looks like one and, I'm not sure that's why, but I ended up burning, by the way, by toasting a 10" speaker, if I'm not mistaken for 250w, A box with a bugle and tweeter, which continued to sound, I didn't move anymore after the accident, but finding out something else I come back here to update the account

    Yo lo alimente con una fuente de +- 60 VDC@10A que recicle de un AVR Onkio funciona bien. Le inyecte señal con una mixer behringer al parecer tiene buena sensibilidad. Lo conecte a un bafle JBL JRX 215 y lo mueve al 100. PROS: - Buena potencia - Buena definición - Conexiones mínimas - tamaño compacto - Buena protección térmica CONTRAS: - La resistencia de 10 ohms que esta cerca de la salida saca humo si no tiene una bocina conectada a la salida. - El inductor se calienta demasiado. - Al conectar con otras bocinas sin crossover pasivo, los mosfet se calientan y se apaga el amplificador.

    As small as it is, this thing makes a lot of noise. Take care not to blow up your speakers! You need a double (+ and -) power supply, at least +50V and -50V. As for the connections, they are a bit unclear but here they are. Take the pcb in front of you with the fan on the left and the blue connector on the right (see attached photo). The connections of the blue connector from top to bottom: speaker + speaker - +60V GND -60V The connections of the white connector from top to bottom: input ground input positive
