My unit, S/N 44xxx, is giving me fits w/ neutralization.  C-77 is a 12.5 =
pf in the schematic but 6pf in the radio.  Most TR-4's seem to show a =
12.5 for C-77.  My radio also has in the schematic a C-226 which is 1.5 =
pf made up of the capacity of a wire routed close to the bottom of one =
of the 6JB6's.  Would appreciate hearing from anyone who has a  TR-4CW =
that can look into the final cage and correspond with me.

Thanks Joe k7mks
