Controls on my amp

Controls on my amp
I have a "SigBal" a "Plate" and a "Bias" control. I understand biasing amps and stuff I just don't know how to adjust plate voltage and Signal Balance. I'm guessing I set the bias voltage to what is good for both tubes then set the SigBal pot so the tubes are as low a difference in ma as I can get.. am I right? As for plate I'm guessing that is Plate Voltage... I have 6550's in place what voltage do I set these at? I also don't where to measure the bias on this amp and how to do that.. I want to learn this because I don't want to take it to a tech.  
Thanks for any help you can provide..
