Need help with power rating my DIY Build. I have a MYJG-50W PS paired wit ha Cloudray CR-50W tube. Tube is rated for 50W max 70W

Tube has a max working of 19mA, triggering of 4mA.
Power supply has a max 22mA
I have digital Ampmeter.

At 30% power i'm hitting 19mA.

I did find that my max on ps is 25mA, that came in around 35%

Do these number sound right or is my Ampmeter off?

I guess I don't understand what you are looking for?
At 30% power i'm hitting 19mA- is what is operative, that should be your max power. What the actual power is would take a power meter [similar to Russ' Dohicky], only calibrated to read the temp rise on a block of metal within a certain number of seconds of your max power. My machine hits the max current at 75% power on the controller, my old machine was 45% power. The % power is a relationship between the tube and power supply.

i understand now.
And i would use these settings within LB as my min and max power settings. Any powerscale would be using these limits.

Thanks Gene for confirming.
