Hi guys! What is the correct bias setting for the driver in a EPT3600-14B board. I have a Midland Alan 8001 for repair, same board as SS-3900. The radio works fine but the driver bias was set to ~80mA. I found different service manuals. Some say the driver bias is 10mA, some say 50-75mA. In both settings the SSB sound is good. Now i'm a little bit confused what is correct. Can somebody help? Many thanks!
