NPN Sunflower


New member
To build this with NPN transistors, could I just remove the chip and jumper the pads for pins 1 and 5?

I have some NPN silicon transistors and want to try transforming the Sunflower into a Meathead.

1) Omit IC1 and C5
2) Reverse C1, C2, and C6
3) Install a jumper between pads 5 and 8 of IC1 (just because they're closer and on the same side).

Don't reverse D1 or the LED.
Potential dumb question: to build an NPN Sunflower, beyond what @PedalPCB said, would I also need to reverse the wiring of the positive and negative coming from the DC jack?
