My DSL modems 9V adaptor burnt so I'm using another adaptor (output 12V) for

Just wanted to know if this may damage my DSL modem?

Pop it open, trace the power circuit, see what the parts in it are
rated for. You didn't mention whether either adapter was regulated or
not, and what their current ratings were vs the rated power
consumption of the modem instead of just peak requirement, which if
you're lucky will be in it's manual and somewhat accurate.
