Thanks neil! you fixed it! i traced it down to one solder point on L6 which visually looked like a perfect solder but the enamel was not actually burnt away. i got lucky in that there was a little nub of magnet wire sticking out of the solder point and i accidentally bumped my probe onto the tip of the wire while i was holding it against the solder.
i resoldered that joint and now i’m getting 2.5V RMS output. 🙂
