Depends on the amp and the reliability of the tubes in some amps they can last over one year or more.What about when tubes blow out this happens.
I am TORN between Tube power amp and SS power amp.
I planned on running my Hagerman Clarinet with either my Hafler DH-500 (looking at "Ultimate" Audiophile Upgrade sold on Ebay at $975.00 - complete upgrade from power caps, driver boards to Exicon MOSFETs, which has "rave reviews") or building DIY VTA ST-120 which will cost a bit more. Does anyone had an experience on both of these amps? I know comparing tube and SS is like comparing apples and oranges, but hoping your feedback may help me decide. Cheers!
