Hi Bob.
You have to be careful when replacing a valve with one that has higher heater current. You could stress the mains transformer on the heater side but also could stress the same transformer due to higher HT current and possibly the rectifier and output transformer. What is the real point? A few extra watts to blow your ears to kingdom come!
