Transatlantic 15 tube suggestions?

[martinlb]

I've picked up a TA-15 and since I've started playing it I've been wondering about trying different tubes in it. I'm surprised to say this buut as a former "holy grail of tone" quester I've changed and haven't even checked to see if the tubes I've got in it are original. Regardless, I'd love to get suggestions for different tubes. What I'm looking for is tubes that would do what I'll call smooth, creamy overdrive, one in the first channel for a little less drive and a different tube in channel two for something a little bit more. What I'm talking about is overdrive or fuzz, a combination of breakup, harmonics, compression and sustain. I know I may not being clear; it's difficult to put sound into words but I hope I'm at least sort of getting my point across. Suggestions will be much appreciated!
