Thought that a 6SL7 / 6SL7 driver board might sound pretty good so I thru one together. I always like the sound of the Mapletree board so I used the 6SL7 long tail of that design with the 6SL7 of what I think is the "IKE" anyway it sound real nice. I do however have questions on the voltages of the 6SL7 input stage that maybe someone here might be willing to answer for me.
The borrowed front end (6SL7) uses a 100K plate resistor and calls for a 215VDC feeding that resistor with 146VDC actually on the plate. I have 221VDC feeding the plate resistor with 124VDC actually on the plate. I have 1.04VDC across the 1K resistor which would be a little over 1mA Am I correct? If so am I in the ballpark for the 6SL7 operation or am I driving it too hard?
