This is what I love about this site, So much detailed information from knowledgable sources. Thank you all! Imin2u, I will be waiting for your review on the different tubes you will sample. For the record, I never had a problem with the AI in stressing tubes. I had the same pair in for years. The unit actually sends a small charge through the unit keeping them "warm" so when the unit powers up it does not "shock"the tube. Again all, Thanks.

You know Ez2hear I just re-tubed my whole system. In the AI, I put a quad of Tunsgram ECC88, In my amp, Sonic frontiers 80 I put as drivers Tesla Ecc88 (NOS) and EH KT-90. The pre-amp tubes sound wonderful. I do not believe the improvement. I am waiting for the KT-90's to burn in (400 hrs burn in time I hear) I am also turning off my pre-amp when not in use. I have not had any problems with my old pre-amp tubes, but only time will tell. Thanks for the tip.
