Re: trainwrecked espreeso updates
Sam,  
 
I already have a .022uF from the third stage to the PI. I do hAVE 0.1uF caps from the PI to the power tubes. I don't think this should make a huge difference as a .022uF/220 bias resitor will give a high pass corner of 32Hz, a 0.1uF/220k bias r will give 7Hz. The low "E" is 80 Hz.  
 
I think the .022uF will not make a big difference between the third stage and the phase invertor, BUT, I will try a 500pF - .001uF ala Fender Blackface.
