You should be able to get 10,000 hours out of a set of healthy tubes. If you want to be conservative you could change them at 6,000-8,000 hours. Just keep a spare pair on hand in case one dies early.
Mcintosh C 220 pre amp tube life....
Hi Folks:
Recently purchased a McIntosh C 220 pre amp (Store demo) with about 200 hours on it. Any idea on how long the tube life is for a 12AX7 A set of tubes in a Mcintosh? I also bought the MC 252 amp to go with it. Wonderful combination. Just wondering if one listens on average of 2 to 4 hours a day, how long I should go before changing the tubes out. Thanks!
