The 87- is probably the problem. There is a color dot on it
that gives you the part #. Example yellow dot = 87-4 etc.
Use resistor color code...... If you cant get NOS look in the
SAMS they often have the break down of them.
If it were a Zenith double disc cap it would have a 22- part #
and usually be blue or tan.
The 87- integrators were high failure so start there. Must
have put in 100's of them in the good old days.
