Sundial - can it take 18V?

[thinice]

Hello - I picked up a second hand PedalPCB Sundial build on Reverb and love it. My question is whether it can handle an 18V power supply? I am running out of 9V outlets on my power supply. I can't find information on what appears to be an legacy board, so thought I'd ask on the forum.

I’m not familiar with that circuit but, it really comes down to the component ratings they used in the build.

As long as the electrolytic caps are rated high enough it can take the voltage. I don't use any electrolytics rated less than 25v for that reason.

Thanks, I'll open it up and take a look. Only the capacitors are of concern?

As far as safety yes. But my guess is that it may sound different at 18V. What power supply do you have? OneSpot makes adapters from 18V to 9V.

 

[thinice]

It's a onespot and I'm aware of the adapter - that may be my easier solution. Thanks.

Are we talking ab one of the Fuzz face/sunface clones? Sundial would certainly suggest so. Can a fuzz face take 18v even with appropriate electros and what would you be hoping to gain from running at 18v?

 

[thinice]

Yes we are, that's my question. What I'm hoping to gain is an extra 9V outlet. But I can use the 18v to 9v adapter as suggested above.

One way to find out!

If it is the sunflower PCB, that has a voltage inverter in it. Wouldn't running that at 18V cause issues?

Not issues.
It will cause a singular issue once.

I thought it was an old fashion silicon transistor running at +9V. I mean I had no idea it had a charge pump etc.

It is. Of it's the Silismile anyway
Was just cracking a joke...
Edit, no idea what the sun dial is.
Edit 2: guessing it's the sunflower PCB, which has a pump.
