Default Replacing Valves

How often should I replace the valves on my Beard P100 amp.Its recently been out of action for a quick capacitor change and interested if and how often I should replace the valves. (PS the capacitor had to be changed due to the other fizzing on top by the contacts- should this alone jusitfy a replacement of valves?)

How old are they?

The output valves get worn faster than the input/driver ones. The two commercial valve amps I have are both running on their original valves - one is from the early sixties and the other is from '57...

So the valves do not generally get worn that fast

But the sound quality may improve if you replace the output valves. If they are not an expensive type, just buy a set and try.
