You may try it out and nothing can be damaged. But there may occur an
excessive inside the housing as the voltage regulators have to burn more
power. As said - nothing can be damaged but there may occur temperature
stability problems (e.g. the 1V/Oct scale or the frequency offset of the VCO
may change a bit over the time). Consequently I'd recommend to find a 12V AC
but temporarily the 16V AC supply may be used.
