Thanks for the advice Nordicnorm. I did get good results with swapping the 12AX7 and tried a NOS Tele and Amperex and liked the Psvane the best.
How did rolling the 82s shape the sound for you?

Recommendations for rolling tubes on Luxman SQ-N10?
Can’t remember now. It’s been awhile since I’ve had an amp with ECC82 tubes. When I upgraded my speakers to Martin Logan Spires, their 40 W weren’t enough, so I upgraded to SS monoblocks (900 W @ 4 Ohms). I only run tubes in my linestage preamp (6SN7) and phono stage (12AX7) currently. In the preamp I have 2 x Shuguang Black Treasure CV181z and 2 x Sylvania 6SN7 GTB Chrome Domes, while in my phono stage I have 2 x Shuguang Custom 12AX7 LS. I keep swapping them out with Mazda tubes. On some recordings, the Shuguang have the edge while on others, the Mazda has a slight edge? This tube rolling business can lead to madness... ;^) |
Tell me about it! In the last three years that I've had tube equipment, I must have 15 spare tubes lying around. Have you ever tried the regular Shuguang 12AX7's in comparison to the Custom 12AX7 LS? I'm curious as to what you get for the $50 difference for the customs. I'm a big fan of their tubes as I use one in my Luxman SQ-N10 and two of them in my Fosgate Signature Phono preamp. |
Until the Shuguang Customs came along, my regular go-to 12AX7 tubes were either the Psvane 12AX7-TII or Mazda ECC83. I tried to find Telefunken ECC803S' but I kept receiving counterfeits (or really bad tubes) so I gave up. Reputable dealers (like TubeWorld) are now asking US$1,000 for one tube, which is too spendy for me. |
