The differences between this and the '90 Kelly schem are, 1) I have no use for the bright switch, 2) this amp has a 72k grid drop resistor between 2nd and 3rd stages, 2) 22K tail resistor in the PI, 3) the ground resistor in the bias supply is a 56k instead of a 47k so the amp is easier to bias up 6L6 type tubes.
