Simulation of a reversed engineered LFO

Hello folks, today I want to continue the series about simulation of synth modules with LTspice. We start with this module from etsy which we disect and reverse engineer, so that we can build it with reverse polarity protection diodes…​ We want to analyze this module . Lets start with the pcbs: To begin with, we first want to reversse enginnering the two sides of the pcb, to build another pcb,…
