Can you pull the old one and find the numbers on it? It's probably half the price elsewhere.
They obscure/remove markings.
If you know the voltages in/out and watts you can easily find a replacement.
Not sure what it is about the MSP3140, but those things eat what are otherwise considered least likely to die components in
the electronics world, IE transformers and chokes. I vaguely recall someone adding more cooling fans to the controls box which
probably isn't a bad idear.
