screen to plate Voltage differential

2/7/2005 5:28 PM
johnscreen to plate Voltage differential
when considering a power supply, what sort voltage difference to you want between the plate voltage and screen voltage?  
 
in my homebrew dual 6V6 amp, i have a difference of about 12V (plate = 360, screen = 348). i see other guys that have like a 40V difference.  
 
i do not have a solid grasp how pentodes work yet and am trying to learn.  
 
anyone care to shed some light on this for me?  
 
thanks,  
john
