The following quote is from the ModWright XA-5400ES Ultimate Truth Mod web page: "The tubes are purposely driven VERY conservatively to give 10,000-12,000 hours + of tube life."
I'm sure this mod improves the sound quality of the player however, I stick with solid state because I don't want to have to change tubes when they burn out. What exactly does the owner have to do after the 12k hours of use? I assume the owner must mail the player back to ModWright for maintainence, and how much will that cost? How much time will it take? Then do you have to let it burn in again? Is the improvement in sound quality really worth all of that?
I'd like to hear about other mod options that don't involve tubes.
