yeah, I will try switching out the tubes, though i hope i haven't burnt the the siemens CCa's I have in there this quickly. I would love to locate a former melos employee and have been in touch with audio horizons about more extensive modifications including a stepped attenuator, upgraded caps and a power supply that would be in a separate chassis that's just a little outta my budget at the time. If one tube has been burning harder for longer will it die quicker? and will the channel associated with that tube have a weaker output as its days come to a close? This is actually my 1st piece of tube equipment so there's still plenty i dont know.
Oh my... i was under impression that Mark Porzilli was no longer living... Is it true that he is still alive? I do hope so, though I am new to melos it's truly lovely stuff and when I heard mr. Porzilli had died i was quite disappointed someone like him had been lost. Anyway i will email for the LI tech info. But please do confirm Mr. Porzilli's current status here to help correct what might be a rather morbid rumor.
Corresponded with Mark by email as stated above on Dec. 14, 2009. I am not that familiar with the entire Melos thing as I only recently picked up the Melos MA-333 preamp. The tech is changing the attenuator for me. See Mark's email to me below:

Thank you. You're in. We are late but 2010 has Melos opening with the only authorized upgrades and center in the world. They will email you once it's open.
