[getafix48]

Hi

I have managed to have my Ultracube 12 driver repiared, but one of the passives has perrished. Unfortunately Balanced Audio doesnt have any spares.

I need to board up the other passive but am not sure if I need to port the board and if so, what size etc.....

Any pointers will be great
