Guido, thanks for the info. and I fully agree regarding manuals and respect any persons own findings. Allot of ARC owners recommend just as Oneobgyn above has mentioned to stick with the Audio Research tubes but obviously you have chosen to go another route what are your findings.
So regarding the tubes when do you start replacing them and which ones and at what intervals, it seems to me that you refer to your power supply going the quickest.
