If its a leaky coupling/plate blocking capacitor between stages it
will allow current through the grid resistor of the driven stage. One
microamp of leakage across a 1 Meg resistor is one volt.

Actually, there will only be 1microamp of leakage *if* the potential acro=
ss
the cap is high enough to drive that current thru it (i.e., its a
resistance). 1microamp leakage measured on a tester doesn't mean it alway=
s
leaks 1microamp anywhere else and would 'push' that thru the 1megohm grid=

resistor, to result in the 1volt grid voltage error mentioned.
