REL Habitat needs a new amplifier board


I have a REL Habitat that (REL tells me) has a blown amplifier board.  They also say that they don't have access to the amplifier boards (the producer went out of business).  Does anyone know of anyone who could fix the existing board?  Anyone know of a source of boards?

I'd much rather get this unit working than junk it!

Thanx
