I've found it's basically impossible to find a replacement for this board, so I've tried to get mine fixed instead. I've had an electrician try to repair it for me, and he's swapped out all the failed components (of which there were many) except the transformer labelled Z0630D on the schematic. We think this is what's preventing it from working again, as the readings for everything else on the circuit now check out. But I cannot find any information at all about the Z0630D.
So, two questions:
1. Can anyone point me to a source of one of these, or at least its specifications?
2. Alternatively, would it be possible to swap out the KLM-2090 with the KLM-2289 used in the Triton Extreme?
Thanks in advance!
