I think this might be my first build for the year. It's a TPA3116 pcb with a dual buffer sandwiching the volume pot in front of the board. Just a quick concept build using a board I had lying around, hence the quality artwork and plastic jiffy box.
Pretty cool looking! And I haven't gotten into smd yet, so I honestly don't know what I'm looking at for some of it:
Is the big black piece a heatsink for the chip?
Is the circle on the right with "330" a heatsink for a transistor?
I see that you have some smd caps next to box caps. Is that signal vs power circuits?
How do you like those Phoenix style board mount wire connectors in a pedal? I have used them in bigger builds but not in pedals. Good? Bad?
Thanks and good to see you posting again!

All good questions, I'll see if I can answer them properly:
QuoteIs the big black piece a heatsink for the chip?
Yep
QuoteIs the circle on the right with "330" a heatsink for a transistor?
I think it's a capacitor
QuoteI see that you have some smd caps next to box caps. Is that signal vs power circuits?
No idea

They have their place. Makes it easier to hook everything up. These came on the board already in place.

Thanks. I think it's the first thing I've built this year.
In all honesty, all I've done is hook up a cheap populated board to a laptop powersupply, and put a volume pot in between two buffers in front of the board, with a 2200uf cap across the power supply.
This is the board I used, although not this seller. Might have gotten the actual one used from aliexpress but it was a while ago.
