Need ~9V DC from this amp circuit

[mlynn02]

Hello! Relative newbie here, so this may be a simple question and answered already but I couldn’t find it.

I am building this amp (SLO clone)

https://www.rosamp.com/wp-content/uploa ... ematic.pdf

It’s working but I want to add another rely to make the FX loop switchable. To do that so need a 9V DC feed for my relay board.

What’s a safe method and spot to tap some DC off of this circuit? I was going to use a small non-latching relay board that i built from pedalPCB. This one: https://www.pedalpcb.com/product/pcb518/
rely board schematic attached.




Thanks for any advice!!

There is ≈8VDC available across C36 in the slo schematic.
