This is great, thanks! I've been looking into how to create a personal KiCAD library, any recommendations on getting started?

Hi fellow kiwi! I've also switched from Mouser/Digikey to LCSC due to price increases. I went for the Microchip TC7660S due to the 45kHz boost frequency, got an order coming in ~December so we'll see how well that performs.

Some of the ICs are no longer available (eg CA3046), and some of the ICs that Moog have used are a bit questionable (eg charge pump IC frequency is in the audible range) so I’m just wondering how good their actual engineering actually is…

What does SW1 do in this schematic?

hFE changes based on the voltage (namely V_CE) & current (I_C and I_B), if you have a look at datasheets of different transistors, you'll quickly notice that V_CE varies (sometimes 1V, 5V, 10V, etc) as well as the testing method used (usually PWM @ some % duty cycle and PWM width of ~300uS). And...

That’s a lot of bees.

Semi-related, what are some silicon diodes I can use to replace the germanium ones with? My other RAT pedals have BAT41+14ohm resistor in the hard clipping sections, but I don't know what would work well in the octave part of the circuit.

Phew, I’m glad that was cleared up. Thanks for the speedy reply & explanation!

Quick question, I’m checking out the Parentheses and the schematic has me a bit confused. The OCT_1-3 connectors that go out to the 3PDT footswitch don’t make sense to me. Namely, the labeling. Shouldn’t 2/3 be swapped?
