Same supply as a 6500 as mentioned, or at least looks the same. My concerns at this point would be damage to the Bose audio board in the power supply as well as damage to the TAM. I am basing this on the previous owner powering it up under 110. Hard to say what made it down the line.

If it was me, I would hunt down a different supply. I think someone linked to one above. Probably the safest bet. But others may know how far the damage can go.
