MHDT Orchid or Lampizator Amber 3?

I have a couple of Sophia Electric 6SN7 tubes from my LS100. Has anyone asked Jiun about using those in the Orchid?

My Mullard 6DJ8 variant is still on the way to try out in my grannyring modded Orchid, but your experience with the   CV-181-Z is certainly intriguing. I can't imagine though leaving the dac uncovered, and I have no idea as to how I would go about enlarging the hole for the larger tube. Have you given any thought as to how you would  do that, and make a neat job of it? Would be nice if MHDT labs offered a lid with a larger tube opening, but I don't know if they would go for that.

Decent machine shop could do it, only needs it if using 6SN7 or CV-181.

Good point.

Where did you source your  Shuguang CV-181-Z? It appears only the 181-T variant is available in the US.....other than getting direct from China on Ebay. It appears at least some prefer the Z vs T model tube.

Maybe this would work!
