Question about adjusting the balance
@carlsbad2 So the question is, how is your tube bias set? I prefer manual tube bias adjustment so I can match any 2 tubes. Theoretically, an auto bias circuit should do this also, but if you’re getting different voltages, then maybe it isn’t. ...

And all this time I thought I was missing out because I don't have a TT and a LP collection (anymore).   
Question about adjusting the balance
Don’t be put off by "lopsided" speaker placement to achieve center focus of the stereo image. Your hearing and gear are not perfect (L/R balance) Imagine adjusting binoculars. Okay, I just didn’t think that there was anything unreasonable abo... 
How does bi-wiring work?
  I tried (WBC) jumpers on my AZ Satori Shotguns.  I hear exactly what you describe.  It's not subtle, they're staying!  Thanks for the tip. I did the same thing (WBC jumpers) with my shotgunned B&W 805s.  I think it sounds better, but I d... 
Question about adjusting the balance
Thank you, @carlsbad2 , I’ll follow your advice, but since you are a physicist and I am only a retired mechanic, what would the explanation be for the sound pressure meter showing a different calibration for balance with the different test tones? ... 
Question about adjusting the balance
@secretguy  , why is it hard to believe it is a serious question? I use my sound level meter and run test signals with two different test tones and the meter indictates that after I balance the sound level by using one of the tones, when I check ... 
which 6sn7 gives the most air??
I favor 6f8g tubes not for air but for fuller sound. @shkong78  , I just recently acquired the good fortune to have a few pairs to play with in the balanced input sockets of my SLP05.  I am currently playing with a pair of National Unions and I... 
JJ preamp tubes - repeated problems
I recently had a relatively new (about few dozen hours) JJ 6922 gold pin in my preamp went "pop!" then died with the glass badly cracked near the base. Wow--sounds like an epidemic!  Pics?

BTW, The link works on my end. Norton must be feeling overly cautious tonight.

All I get when I click on the link is a message from Norton that says "dangerous web page blocked."  
Signal tube versus power tube, sound impact?
Amp manufacturers know that people are going to roll tubes anyway - it's part of the charm -  so why not let them do that for themselves. That is also what I think, @bolong  .  +1.   
Signal tube versus power tube, sound impact?
I think they are shooting themselves in the feet when they put JJ tubes, which consensus seems to say are lower quality, into their tube amplifiers. Hmmm . . . I just looked at your "JJs suck" thread and counted the positives and negatives, and... 
Cary Audio SLP-5 Preamp Tube Replacement.
I have read somewhere that all tubes interact with each other in the circuit so the sockets has to have tubes in them I have read the exact opposite. And although I realize that this discussion applies to the SLP05 preamp, back in late 2017 (wh... 
Seeking Honest Opinions: Your Experience with McIntosh Audio Gear
I had a SACD player up until a few weeks ago when I sold it @glennewdick  , I know this is the amp/preamp forum, and I also know there is a digital forum, but I have been really curious about the Mac SACD player for a while now.  What did you t... 
I Don't Understand What Determines When A Thread Gets The Axe
Speaking of axed:  did the "Krell equalizer delivered to wrong addy" get the axe?
