working on Marantz tuners, 2270, 2275, notice changes in R-d in some units for the first fet in the front end,
, have seen, 100 ohms, 47 ohms and 10 ohms being used,
was wondering why they do this, is it simply using different resistors to bias the right I-d ?
what happens to noise, gain and bandwidth with different values of R-d?
thanks!
