Can I safely use 12V power supply with Phase II ?

[eh là bas ma]

Hello,

I am considering taking the Phase II circuit out of the enclosure, to put it somewhere inside a digital piano Korg SP170S running on 12V.

Schems :

https://docs.pedalpcb.com/project/PhaseII.pdf

Do you think the phaser can take 12V ?

On Korg schematics page 9 : can I connect the phaser between Q1 et Q2 outputs and both HP ? Is it the easiest way ?

Thank you for your help.

That's not going to be much different than connecting it externally to the L(mono) output jack. The circuit can handle 12vdc, but it is a single channel circuit.
