The other matter is some brand amps will run KT150s, and yes its safe for some, and yet the transformers, power supply, and plate voltage may not always be designed or upsized to drive KT150 tubes properly.
In reverse, my current KT150 amps with much larger transformers and more plate voltage with manual bias cannot run KT88s or EL34s, it will burn them up prematurely. Best to always check with the amp designer.

decooney, Prima Luna recommends the KT150 tubes and they are safe to use in all the Prima Luna amps. They do not come standard due to the $100.00 price per tube.
