NOS Tubes for Rogue Tempest II

Looking for some suggestions replacing the stock tubes. I want a little more transparency or pop yet retaining overall smoothness and good bass. I want to start with the 12AX7's and the 6SN7's first. I was told the Sylvania 6SN7 GTB would be a good one but there are several versions so I am a little confused. Also the same with the 12AX7 what is a good value without breaking the bank.

Jerico I found the NOS GE triple mica black plate that I had stashed to be much more precise and less fuzzy than the stock Sovtek 12ax7LPS so I can relate. Let me know how the Telefunkens workout please!!!

Right on - I believe those GEs are what my amps were supplied with (are they the ones marked with 5 stars?). I prefer them over the Mullard, but prefer the Sylvanias over the GEs (though it's not a drastic difference there, to my ears).

WOW you got some high dollar 5751's with the amp. Those 5-stars are the most expensive GE 5751's.

I used to have some NOS RCA triple mica black plates but preferred the GE's in a CD player I had. The RCA's were a little dry sounding while the GE's were more robust to my ears.

Have you heard the NOS RCA 12AX7 cleartops?

Yeah when I bought the amps the dealer requested NOS tubes with them, I believe.

I have RCA clear top 12AU7s in my amps now and love them (they were a Rogue recommendation) but I haven't heard a 12AX7 (M180s use 2x12AU7 and 1x12AX7 each). Great, another thing to buy!! ;)

I forgot to add the seller gave me a pair of NOS RCA 12ax7 cleartops for my integrated. I have not put them in yet but he said they were a warm sounding tube. It doesn't sound like they are as warm as the Mullards you speak of.

I used some GE 12au7's on a preamp I used to have. They weren't NOS but sounded pretty good and were not very expensive.
