I just bought a new integrated amp. The unit is one that converts from push-pull to triode with a button. I have used push pull before and found the tubes take a good number of hours to break in a smooth out. I have never had a triode amp. Now my question...the push pull mode seems to have smoothed out pretty quickly but the triode operation is still a bit off. As these are the same tubes, is this normal? Ie; do the different modes break in at a different rate?
