How long do the Tungsol 5881 typically last? I feel like I got some volume loss on the nova. Is it time to swap the power tubes? Or run it till it sounds bad.

New manufacture or old stock?

If your tubes are more than a year, and you sense the power tubes are creating a volume loss, then you should get a set of tubes ordered. If your amp starts acting really wonky, then shut it down until the new tubes come in. If the Power tubes short out as they are dying, then that will create an event that could take out the rectifier and possible a screen resistor. Not very common but it happens. You could also have a pre-amp tube issue which would probably be V1 or v3, if v3 is the phase inverter tube. I would try a different Ax7 in V1 and see if anything changes. Try v3, if that doesn't change the performance, then try the power tubes. I recommend that you don't wait until it sounds bad.
