Yes I know but that's one piece of equipment I still have to buy and they aren't cheap.
Thank you, I will set it at this, leave it for a while, see if it drifts, how heat sinks feel and check scope for crossover although that's probably not very accurate.
Thanks for your help

Bias stays nice around 15mV (+/- 0.5mV), heat sinks are slightly warm and I don't see any crossover notch.
The only thing left to do now is check out that power meter and see what's wrong with it.
I did already verify and they do get the same voltage across their terminals.

Last problem has been solved, I disassembled the power meter that was weak and completely cleaned it : the back spring got stuck to the back of the casing. They now track pretty closely.
