Re: Cathodyne PI
What would be the best candidate from the following tube types: 6SL7, 6SN7, 12AX7, 12AT7? An EF86 is the front end of the amp which will drive the first triode of the tube I use (no tone stack). The available B+ for the tube will be about 260V. The PI will then drive a pair of cathode-biased EL84's in ultra-linear.  
 
EF86-->volume control-->triode-->triode PI-->EL84's  
 
What would be the proper values for the plate and cathode resistors on the PI triode? Thanks so much for your help in this matter.
