Low power out from Ameritron AL-811H Amp

Hi,
Again, I am shooting in the dark here as I am a complete green-horn on ANAN!
Before I transitioned over to ANAN I used my plain-vanilla Ameritron AL-811H amp without any issues and if there were any it was fairly straightforward to fix it.
Now, when I get on 40 meters the amp doesn’t put out as much power as it did in my “traditional” transceiver days. Perhaps I should use my Bird 43 watt meter and “calibrate” the 7000 DLE MKII to see if there is a difference. Normally, I use max 50 W (depending on the band) of exciter power and can easily get 600 W out on 40,20,15 and 10 meter bands. Now, I can’t.
I am barking up the wrong tree on calibrating the ANAN or perhaps there is another reason? I did notice that when I out the multimeter on “MIC” on the ANAN the peaks don’t hit 0dB as it should. Likely I need to work on that (and also calibrate the PA in the ANAN) first?
Best!
