Hi everyone
I'm trying to set the BIAS of my citronic ppx900. As you can see in the schematic there is a pot. added to set it. But my question now is, how do I know to which value to set it to?
I've read that I should lift the fuse and measure the drain current. Also, the internet says it is often tuned quiet agressive and that they do run hot in idle mode. But then again, what is the value related to that? Also, if somebody would use a different method for example by measuring dc offset etc. you can let me know. I'm new to working with amplifiers. Schematic underneath this post and also some datasheet graphs.
Thank you!
