I was going to send a private message to Jeff but instead I'll post my question here since others may be interested or have the same or similar question. Jeff, regarding the Kinetix what kind of life expectancy can one expect from the three 12XA7 tubes inside and how would one know that either one or several of the tubes needed replacement? If one or more of the tubes went out would the amp still work? Since the tubes are not visibly lite up being covered with a solid top plate is it possible that someone could get a brand new amp with one or more tubes not being functional where the person would not even be aware of this, or would the amp distort or not even play under this condition? Please note that I don't suspect this is the case with my Kinetix and also realize Genzler QC is as good as it gets in the industry but am curious since the tubes inside are not visible. I previously had a Mesa WD 800 and really liked the fact that you could see inside the chassis that the single tube was lite up. This is not the case with the Kinetix. Thanks
@Moonskunk ---- Good question about tube life. Your tubes in the Kinetix should last for years without issue. And as Andy said, seeing the tubes and the glow of the heaters is not a good indicator of tube functionality. If you were to have a tube issue, you would hear functionality issues or excessive noise, etc. It would become obvious.
There should not be a concern about tube life.
Naturally there are users that would like to experiment with various tubes in different postions, but we believe we've selected the best tubes, and the highest grade availalble for each circuit within the Kinetix 800 design.
And for this design, we did decide not to show the tubes with some sort of window or grille. We did that with the Streamliner and we felt this amp needed to be a complete departure from our previous work. Also, I kind of feel that showing "glowing tubes" in an amp design has kind of been overdone over the last decade with all sorts of guitar and bass amps, etc..
Please plug in and enjoy.
Let me know if you have any specific questions.
