just overall use of the amp . As the time of over 1000 hours has been logged 2 of the
original set of Gold Lion KT88's i installed have lived their life . 1 last week and 1 today .
Both ended with grid shorts . I replaced the fuse with a 4 amp mini breaker i purchased through
Webber that makes the Copper Rectifiers . It mounts through the hole where the original fuse
holder was . It's just more convenient than using a regular fuse . My amp is on a permanent
wall shelf in the basement where it's nice and cool and plenty of air around it . It's
the place of many past amps .
So my finding it that the average power tube life is around 1000 + hours per tube .
Whats your take on this .
