I posted on this thread a while ago about installing a 6DJ8 in my Orchid via the 5670/6DJ8 adapter. I think in my post I mentioned. Something along the lines of the sound changing from that of a Baldwin Piano to that of a big Steinway. Well, I now have a Western Electric tube and the Tesla tube that are both on the MHDT Labs recommended Tier 1 tube rolling list. They all sounded good, and they all sound slightly different.
