Can you do anything to make power tubes last longer ?
I see. Before 60s Sylvania were good, I’ll keep it in mind, thank you. Kevin didn’t specify, by the way, he just said Sylvania and Brimar. Brimar lacks Mullard’s sophistication and has a recessed midrange, both are no-no to me. No, I’ll get XF2, ... 
$3500 floor standing speakers used. What would be your choice ?
I thought that Dynaudio required a lot of power to sound best, they are usually used with powerful transistor amp, I heard.

If we could go into the details, assuming the same Avatar amp, what difference would I hear between same level ProAc, Tannoy, DeVore, Sonus Faber and AudioPhysics ? Going from $3500 to $5000 might be a possibility but I must be sure it is worth it... 
Can you do anything to make power tubes last longer ?
When I bought the Avatar I talked to Kevin about tubes. He recommended selected Chinese 12AX7 for the preamp and phono that he had, Brimar or Sylvanis 12AU7 vintage for driver and, yes, Mullard or Gold Lion vintage for power tubes. But I didn't wa...

It would certainly be interesting to try vintage Amperex EL34 but I am currently on the hunt for Mullards XF2 and getting close to them. XF1 would be much more expensive and even more difficult to find. Then there are first generation Mullard EL34... 
Can you do anything to make power tubes last longer ?
Alright, I will join you in the abandoning the ritual of using white gloves while handling tubes. And the grip is indeed worse than bare hands. Having extra set of all needed tubes is of course always a good idea, well, some tubes are really expe... 
Have you been enjoying your Gryphon Diablo 120 integrated ?
Of course, I don't mind. I heard rumors that Diablo 120 was more musical than Diablo 300 and that some people who didn't need the power of Diablo 300 chose the 120. But I heard it a few years ago when I was considering it. Perhaps now it is diffe...

gs5556, how do I check heater voltages ?   oddiofyl, I could have a second system too with my old SS amp but I just wouldn't listen to it ! Those new EL34 Mullards, are they new reissues or vintage ?

corelli, this is the first time that I "meet" someone who is familiar with these speakers. Yes, set up is critical, and if you push them too far they get out of control. But at moderate level with especially smaller scale acoustic music they sound...

Current speakers are Michael Green Audio Rev80i free resonance design. Let's say their sound signature is close enough to Grado RS-1 wooden headphones. I play at moderate levels, many kinds of music but not hard rock or big orchestras. I don't to...

Lower voltage.. I use PS Audio regenerator that outputs 120V constantly, if you believe it. But I noticed that, yes, input voltage is sometimes above that but never 125V.  
Revox Introduces A New Reel-To-Reel Deck...$16k
Yup, I saw it on picture. I'd rather get old Studer and have it serviced and calibrated. Too expensive, anyway.  
Can you do anything to make power tubes last longer ?
Yes, bias is adjusted individually for each tube, and I follow the manual. There is no range stated, there is a black dot you aligned the needle with, that's all.  
Can you do anything to make power tubes last longer ?
I wouldn't replace expensive and hard to get tubes unless they do something audibly/visibly wrong. But if you use new productions tubes, yeah, why not ?  
Can you do anything to make power tubes last longer ?
Oh no, I never leave it on when I am not in the house, or overnight, for that matter. Though my VAC has some circuit that shuts it down if power tube runs away.
