How might this design vary in functionality compared with the TreasureLinx Mirage Ultra 1?

Here is a great little VCO circuit Mickstv posted back 2-3 years ago and I've had veroboard version for use on my bench for so long..it finally gave out so I decided to put it onto a PCB.
I added extra decoupling, changed Fet and added option for audio amp connection..all vanilla stuff.

Had 10 Blank PCBs made by PCBway for $25 Au and $20 of that was delivery.. Thanks for the heads up on that Moodz.

I normally use a digital audio version of this but sometimes analog is a better fit and Mick's circuit was worthy of a pcb
It is SMD using mainly 0805 parts.



The original circuit is posted in the Minipulse Audio section..
