Fender Super Champ XD Needs New DSP Board

[gmeades]

I've got a Fender Super Champ XD that I'm told needs a new board to get it working again.
I believe it's the DSP Board (see attached pic).

Fender just wrote back and said they no longer have the part...

I've been looking at Amplifier Parts websites that come up on Google,
but all they seem to carry are tolex, handles, tubes, etc.

Does anyone know where I might be able to obtain a DSP board for a Super Champ XD from...?

Thx...
