For what it's worth... I only use my AIM3A as a line stage, so in the phono section I put Tungsram 6922's and in the line stage I use 60's Siemans CCA's. I've had them in there over 2 years now and they still sound amazing. Am I the only one who's had luck with this preamp? I just haven't had any problems yet. Knock on wood...
Bad Tube in an Audible Illusion M3A
After using an Audible Illusion M3A preamp for over three years I finally had a tube go bad. I noticed a loud whoosh in the right channel and traced it to the phono section. By swapping the tubes between left and right I discovered it was the tube on the right side causing the noise. The tube had only about 300 hours on it.
I've had tubes that I replaced because the highs diminished, I have a tube in an amp that rattles when it powers up, but I've never had a tube get noisy. Why does a tube do this? It would seem the tube would short out or just stop working.
In hindsight I shouldn't complain, this is the first tube I've had go bad in the M3A!
