Four Hour Tube Amp Warm-Up

My Primaluna Tube amps require a 4 hour warm-up in order to enter the Glory Zone. My previous Muzishare X7 tube amp was the same. Just wondering if this holds with the experience of other tube ampers.

If it took 4 hours 1st I’d look for new tubes andif that didn’t work then I’d be looking for new amps
