I play a lot of LP recently and last night I noted that sound was quite bad. It was like a bad electricity day only atop of it sound has some kind of odd digitalization atop of everything. Of course I was blaming the PurePower 3000 but then I realized that my FM and my digital sounded fine. My mono arm loaded into another phonostage was fine but both of my stereo arms: reference and daily arms were horrible. In fact I did not recognize that reference arm was bad as well and I was fighting with my daily arm. I did some modification on it and I thigh that was the reason. Apparently it was not as my reference arm that I did not touch sounded in the very same way.

So, I think my “End of Life Phonostage” has died. There is nothing in there that might die and I did not touch it sine I move but something is wrong in there. The tubes died. I use the same tubes for 12 year in this phonostage, I did not test then for 5-6 year but 12AX7 shall not die suddenly like this.  I did have fine sound 2 days back, it shell not take foe this tine one day to die. Anyhow, this requires investigations there is something very wrong with this phonostage now.
I can’t not find any other words then “what the fuck”. Two day back it was fine and then all of the sudden this crap is coming from two of my stereo arms!  There is nothing in my phonostage that can die like this. I know the sound of dead 12AX7 – it is not it. The sound I have has full body with full LF but with some kind withering in upper MF. The higher it goes the more it breaks itself apart. It is not too huge but it is there and I hate it. Whoever heard my playback know that it goes up in frequency and amplitude there is no event – it very smooth, natural and non obtrusive. Now at higher it goes and as louder it gets it has more and more almost some kind of mechanical resonances overlying over sound. Dead tubes would not be doing it.

I did check everything in phonostage and everything measurable in there is perfect. The tubes are fine. Nevertheless, I did replace the tubes with no effects. Might be the transformer got burned by some kind of stray solar wind? I have no idea what to think. CD, moro arm, tuners and even tape machine sound fine but the arms connected to this phonostage are no good. Now, I need to recall all even over the last 2 days and see what the hell went wrong. I cooked pork shops on Saturdays, is it possible that God punishes me?
