Do micro wave ovens loose “grunt” with age? I find that I have to heat my muslie longer now to get the required temperature compared to a few months ago?

Your previous thread on exactly this topic, sir.
answered this n the other thread, bob
the megnetron that generated the radio energy is a valve, like in the old days (CRT TV picture tubes too), the cathode output declines.

the parts that wear are the bits that produce the electrons

dv, thankyou, and I apologise to you and everyone else, my short term memory is bad and getting worse, thanks all and again sorry about this.

I hope things go well for you.

I agree.
Even got the title wrong, shit ! Micro Oven instead of Micro Wave Oven.

Thought you were planning a mouse roast.
apart from low cathode output there are some other possibilities
- moding which is when mag valves output is not clean, well it’s dirtier and may have output other than the main fequency
- related perhaps it may go off frequency
- cracked mag valve magnets
- i’d guess too if the HV capacitor on the rectifier/V-doubler loses capacitance that the HV anode voltage can be reduced
- then there are intermittent faults (assuming duty cycle from control side is all operating properly) like one of the mag heater spade lugs is not making proper contact.
