Since people will no doubt want to know about the 5457s, hopefully the pic covers the what and the why is because I wanted an easy way to socket these SMD trannies.

The rest should be pretty self explanatory. Worked first time, probably because I took my time and measured everything first, and paused several times to clean the PCB with IPA. I used a B25K instead of an A25K for the Mids pot because that was what was available.

Left LED is yellow and right is orange, though the yellow is pretty orangey anyway. They look pretty similar in the pic but they're noticably different in reality.

I need to explore the trimmers a bit more, but with all 3 at noon it sounds really good. The Boost side is dirtier than I expected, and the other side is pretty clean, but pleasantly so. Definitely adds a nice warm glow to the sound.

Great looking, and I agree the warmth of this build was a welcome surprise.

Why are the transistors soldered crooked?

Why are the transistors soldered crooked?

Super cheap adapter boards from AliExpress.*

If I soldered the transistor on as intended, the legs would be (L-R) S G D. Slanting them like I do the legs are S D G. It's only slightly more difficult to solder them on at a slant. EDIT: If I didn't slant them, the legs would need to be twisted to line up with the PCB. This way they're straight.

I have no idea why these adapters are designed the way they are, or how they're intended to be used. All I know is that they're cheap. Very cheap.

*Not the seller I bought from, just one of the first that came up when I searched "SOT-23 adapter" on AE.
