Almost zero probability in the 2N3055.

BeO is a super combination of thermal conductor, electrical insulator. But in the '3055, the only insulation needed is the two leadout pins - which are glass-bead insulated. The die inside is soldered directly to the header, which is soldered to the base. No insulation needed!

If it DID have BeO inside, you wouldn't be able to throw in in the bin...
