Thanks for the reply. I have currently changed out 12AU7s and I think there were two that were bad (between the ones that were originally in and the ones I used for replacement) which complicated the troubleshooting. At this point I think the problem is solved, but I am presently running the pre and waiting to see if this issue returns. Am using Shuguang tubes that are almost new.
