Hi,
I am trying to squeeze some information from all of you again.
The question is: what are the advantages of using Gary Pimm's CCS to load a tube compared to a mu-follower?
Gary's CCS shows a load of over 100MegaOhms, while a mu-follower could probably get up to 2Megas or may be a bit more. Is that the only difference?
I would like to hear your experience if you tried one, the other or both.
I was thinking on using a CCS to lead a 76 tube (input stage), capacitively coupled to a 211 grounded cathode (output stage). The change from 100Megas to 2 Megas does not change much the slope of the AC loadline (considering a 100K grid resistor for the 211).
Any thoughts and comments will be very appreciated.
Regards,
Rada
