DC300a biasing

11 April 2016 - 10:08 AM

Im a bit confused.Im trying to set the bias on my dc300a according to the service manual.It calls for .310 to .345 mv across resistors 132,232,139,239 on the heatsink board.You do this by adjusting  {changing] the resistor at the plugin sockets on the main board. Are those mvs Ac or dc? The manual is a bit confusing.  Also do you think the amp gets adequate cooling without those heavy heatsink boards with normal home use? Thanks,Cronie
