Hi Guys, (and especially PRR)
As always, I am absolutely thrilled by all the responses I have received on this subject, and vari-mu in general. I cannot thank you guys enough. I actually feel that I have LEARNT some fascinating stuff.
With my u74/fb76's, it seems I have the basis for some experimentation sitting on my bench, without having to build anything. Excellent! Basically, I want to try to end up with something with a gentler slope.
PRR suggested that FF would probably give a "soft-knee and an erratic limiting level". I am guessing that the u73 must have some clever stuff goin' on. The u73 goes from linear to limiting in approx 6dB. is this because of the "The large G2 resistor semi-linearize(ing) the V/I curve"? Would running the tubes with a smaller G2 resistor make it into more of a compressor? How about if we run the E99F's in triode? would that reduce the slope? I will definitely be trying out all of the above, but would welcome any input before I start!
Kindest regards,
ANdyP
