Alternative to 12AX7-EH tube needed...new to tubes
I would definitely try a 5751(GE black plate or Tung Sol))which has a gain factor of 70, while the 12AX7 is rated at 100, so you would have a 30% gain reduction. I think the 12AT7 mentioned by Yogiboy and rated at 60 might be too drastic a reducti...

Can tube rolling change bass?
Totslly agree with Mapman. I have rolled more tubes than I care to remember and changes in bass are mostly subtle and could be considered a tweak. Deep bass is mostly derived from woofers and subwoofers and the equipment driving them, not from tubes.

Problem with Analysis Plus Silver Crystal Ovals?
Weird that only one cable is marked??!! Makes me suspicious that one cable is a second. My suggestion is to call them back until you get a technician to answer your questions. Afterward, I would probably want to return them for a pair in which bot... 
Is Hi-fi getting more expensive?
Yxlei I am hoping Ferrari heeds your advice. 
ARC Ref 3 bad tube?
No matter what, the white residue indicates this tube needs to be replaced. In a perfect world, a 6550 should last for 3,000 hours, but there is no guarantee that it will. Tubes sometimes fall way short of the expected life and that is why you wil... 
Cable
Works fine if you like the sound of that loom. I once had all Nordost and though they are very revealing and neutral, I thought they were too cold. I have also mixed cables from different manufacturers with success. Going after the sound that is p... 
I need your advice on system for a non-audiophile

Can the glass on a tube be repaired???

Want to Blow Up My Stereo
Sounds likje you tried everything. It almost sounds like the balance is deliberately favoring one channel. Do you even have a balance control? Are you sure that all of the speaker drivers are working properly. Maybe you can try a different pair of... 
What is your favorite tube for a preamplifier ?
I think it depends on the build quality of the preamp more than the tubes. I have had a preamp that used only the 6SN7 family of tubes vs the other that used the 6922 family of tubes. The second pre with the 6922's sounded better because it was a ... 
equating class A to class AB SS amps?
Just an after thought, AB also runs a lot cooler than class A amps. 
Most overlooked LPs in the last 20 years
20 years is a long time, but one LP that sticks out in my mind is Zooropa by U2. I just remember all the fuss surrounding it and I think it was overlooked mainly because most people thought of it as techno trash.
