I have a sick DX70 (not TH). The output power on the hf bands has
gradually fallen from 100w to less than 50w over the last few months.
Same effect on all bands, except for 80m, where the power has only
dropped to about 80w.

I've independently verified the external power meter I use against a
Bird wattmeter, and the power input is still 12v DC, so it has to be the
radio.

Ideas anyone?
