Well , I have assembled two of these folling the instructions and neither of them work 
.
I have used the resistor for the 4 ohm 10 - 2000 watts configuration.
The amp is the Numark Dimension 4000 and is in bridge mode - 1900 watts into 4 ohms. The speakers are JBL JRX125.
All the solder joints are sound etc⌠Anyone got any ideas?
Make sure T1 and T2 are not swapped
Make sure zener diodes are put in the correct way round
Same for the leds
Check orientation of the diodes
If you cannot get it to work, please mail kit to:
Velleman Kit Repair Dept.

Thanks for that. I have checked the things you mention but to no avail.
What will happen if i send it/them to the address you provided?
Kit will be fixed and returned.
If problem is caused by manufacturing error, kit is fixed for free.
Otherwise, a small fee will be charged (less than price of the kit, shipping not included).
Thanks for that. One of the two kits I bought I have experimented with by reversing all the leds but still no go and this kit (board) is now damaged so I will not be returning that one. So when I return the âuntamperedâ one to you please could you advise me as to the problem with the âgoodâ board so that I may repair the damaged board. Thanks again for your time and help.
