How often should you replace tubes?
I just replaced Gold Lions in my preamp and they had been in there 5 years+. The system is on an average of 5 hours a day.
The new tubes have tightened up the sound and expanded the soundstage. |
How often should you replace tubes?
Here’s a pretty good read on the topic from our dear friend Dan...

Well I certainly can’t keep an accurate enough captain’s logbook to track 7000 hrs.... :no:

I think it varies by tube and component. For my AR preamp the large 6H30P is 2,000 hours the rest of the 5 smaller tubes it is 3,000 hours according to Audio Research. But after about 2,000 hours one channel developed an intermittent whistle. So I changed all the small tubes and it went away. There recommendation may be based on optimal performance, not how long they will work. I have “heard” there is a performance drop off, but I cannot confirm from experience.

I'm interested in following this thread as well...
with 12 tubes in my pre-amp, I've been doing a lot of research on what's the best way to go about avoiding degraded sound. |

Same with the bigger 6550 tube. However there are NOS versions of this tube that are in high demand. This is why you don't hear many people talking about tube rolling with Audio Research. There's not much you can do. |
It was Victor Khomenko of Balanced Audio Technology who first introduced the 6H30 to the audiophile world being that he is from the mother land of the tube and knew it well.
Yes, that tube was designed for maximum longevity and reliability for space and military applications. :smoking: In terms of sonics of that tube? It does its job, the BAT gear with that tube sounded richly textured in harmonics with a slight tilt to the darker side of neutral which bodes well with many speakers, rooms and music genres. It just works, no need to look for all the "cliché" replacements. |
