NPN Sunflower

[greggerypeccary]

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.

You need to reverse anything polarized as well. Caps, diodes etc

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.

whoops yeah, my bad. Holiday Baileys coffee and troubleshooting don’t mix

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?

Nope. The DC jack wiring stays the same either way.

Thank you! I have a few BC108Cs lying around, will try to give them a home in an NPN Sunflower soon.
