12V to 15V circuit conversion

[1wildthing]

Hi there, I would like to insert the attached circuit block in a build I'm working on. This circuit works on a 12V basis but my new build will work at 15V.
All the components used in this circuit seem to work even on higher voltages but I wonder if they need to be adjusted in some values.
Could you please share your thoughts with me?

What are rw12, rw27?

Should work fine at 15V. The transistors will run at 20% higher current, but I don't think that matters here.

RV12 and RV27 are dual gang potentiometers

..this is a bandsplitter, overdrive, then re-combining? Note that if you change any of the three levels, the re-combination won't add up no more, and you get phase smear around corner frequencies anyways. No free lunch...

If in doubt, make the 10K/68K resistors around transistors some 20% larger

Yes, it's something I'm curious about, it's a kind of tri-band overdrive. Thanks a lot Jackob!
