That's a really cool build @postalflunkie, especially the maple enclosure!

@postalflunkie, very nice build! Love the way you made the enclosure. Grtz, Bert
Fair enough!
I put together my second board over the weekend. Unlike the first time, the HV power didn't fire straight up, which is annoying. I don't like troubleshooting.
Had a similar problem at first. I couldn't source a BC546 so substituted it for a NTE123. Turned out the NTE is the same specs, but the pins are reversed. De-soldered it and flipped it around and it worked
Hey quick question; I'm starting this project myself. I bought the 2.0 version because I wanted the clipping section and the bright/mid switch. I'm looking at my board and documents but I don't see anything about a potentiometer for the Drive function. Just a Vol, Bass,Mid,Treb, a Treble switch, mid switch and the switch for the clipping portion. There's one trim pot and one resistor that the notes say can be used as a trim pot to adjust the clipping. Is that what you guys are using for the drive?
Another question, I can't seem to find an answer for in the build manual. What is CLR and CLR1 supposed to be? I see two components on the pcb labeled that, both right next to LED 1 Aand 2, but theres no mention of a CLR in the BOM
I think I figured it out, the drive pot is the volume pot, and you guys are wiring a separate volume pot right before the output jack instead of the output jack wired from the board.
and the CLR is a resistor to adjust the "dimness" of the LED which is optional.

Sorry, I've not been online much recently. Yeah, I ended up with two volume pots - one was input volume and one was output volume. The input volume could be renamed gain, and I found it to be very high output so the output volume helped tame that.
