The new tubes that replaced the old did not sound much different than the stock tubes. I only noticed much more tube noise with one of the new tubes, and the fluttering noise ceased. Thats why I put the old tubes back. I noticed the diminished highs after i put the old tubes back.
I have heard the cell phone fluttering before, but that usually only happens if I am very close to my equipment and I am about to receive a phone call or text, then the noise goes away. I have tried a third set of new tubes with the same result.
I guess I will have to send my unit into Aesthetix to be looked at, or re-tubed.
Oh, and I did double check all of the settings in regards to loading, gain, and interconnects. Everything was set correctly. Thanks again for all the suggestions.
