Default TDA 1541 voltages

The 1541 is specced to reciewe 15 volt +/- and 5 volts. Is there any margins for this levels. I have a powersupply supporting 12 volts +/- and 5 volts.

The spec says Vdd = 4.5 - 5.5V, -Vdd1 = 4.5 - 5.5V, -Vdd2 = 14 - 16V. However, in the Marantz CD94 -Vdd1 = 6V, -Vdd2 = 13.5V. I think the clean stable voltage is more important than the actual value. Vdd (+5V) seems to be the most critical.

Just for clarity, you need +/-5V and -15V.
