Thanks Martin. There are a couple of stays connecting the panel to the amplifier, these can be released by inserting a screwdriver from the side and the panel drops forward. 3 screws release the PCB and the switches drop out. The small fins that hold the 3 switches in place were all damaged to varying degrees. After putting the switches in the correct

Was checking the mode switch on the front amplifier panel and switched it Left to Off. When I tried to switch it back Right to ON the slide switch was loose and it wouldn't switch back on! Feels like the switch is broken, do I need to dismantle the speaker to fix this?

Thanks for that, does this mean I need a 5V 2a DC power supply? Michael

Hi I purchased a 7.1 switch box in Japan but lost the DC power supply in transit. My contact in Japan is not willing to supply a replacement and as I don't know the DC voltage I can't purchase an equivalent in the UK. If anyone has any information about the DC input voltage for this box I would appreciate it. ThanksMichael.
