Power supply for CD-PRO2 LF

[GIPIONE]

Now is possible buy the last version of CDPRO, and I think built the power supply, we are a DIY and is satisfactory al least a little part of electronic.
Now the data sheets explain that it necessity of :
9 volt +/-10% normal for the motors , no very difficult o expensive, a simple power supply.
5 volt for servo-decoder-CK-and DAC on the board.
That is very important no noise, speedy i.e. a super power supply.
Now project and built it is no problem, a question is delayed ; when turn on before +5 volt after 2” o plus delay on 9 volt; when switch off the reverse.
Same of you have a simple idea with electronic delay without timer 555 , o other , and rele?

Thank of all.
