Hi. This is my first build. I hate to hi-jack an old post, but I'm running into this same issue with the triangle beaver and understand about the head-to-tail alignment, but I seem to have soldered connections on both ends (head-to-tail AND tail-to-head, in a loop). Should this concern me? I see you saying that these are parallel, so it sounds like I'm OK.
You are indeed OK. That's how clipping diode pairs work--connected head to tail at both ends. Because an audio signal is AC--a sine wave that goes positive and negative--one diode clips the ascending signal while the one of opposite polarity clips the descending signal.
