Kray, I agree with albert. Get some NOS from Andy's, tell him what amp you have and how it's configured and your price range, and personal preference and Andy will hook you up. He's the best in the business!
12AX7's & 6SN7.....
I recently purchased a Consonance Opera M99 integrated. I love it. I am now wanting to replace the tubes that came with it with NOS tubes. I am leaning towards Telefunkin and Mullard, but was wondering which will be the most quiet? i get a good little hum coming from my speakers now, and i'm aware that it's the nature of tubes, but which tubes should i use to get the buzz to a minimum?? it came with Sovtek's 12AX7's as the first SRPP stage and Shuguang 6N8P's (6SN7's) as the driver stage. thanks for any info you can provide...
