Please Help ID Space Command Parts..

The pictures below are taken from a 1958 Zenith Space Command with a chassis marked 18C24Q. The parts I am trying to ID are contained in the coil can designated T4 in a schematic I have of similar models. The first picture shows the part that I found to be open. According to my reading of the schematic it is indeed a coil. It is marked either L5 or L6 on the schematic. I am fairly certain it is L5 which is shown running into a diode symbol. L5 has no value but L6 shows 1 ohm.

Long story short I am trying to identify the components in both pictures. The supposed coil in the first shot looks like it is made of, or encased in some kind of black gelatin and bears a green dot which I guess signifies its value.

The second picture is viewed from the top of the chassis with the can removed from T4. At 11 o-clock I see what looks like a short, light colored resistor with three color bands, and over to the right is a very small component that is a little smaller than a 1/4 watt resistor and looks as if it is clear, with color bands. Is this a diode? In the schematic there is a diode symbol designated as X1. Is the tan thing a capacitor? The schematic shows two capacitors (C17 and C18). There is a disc capacitor at 7 o-clock. I do know that at least.

I have been harping about this set for a few years here, all the way from trying to get it to work after being stumped following a recap, to trying to give the damn thing away. I can't believe the absolutely nobody wanted this clean, early remote set, with a strong 24" crt. The set is so nice I don't have the heart to do anything but give the repair another chance as the set would be a great daily user if I could ever figure it out.

For the record it has/had the same symptoms with both the old and new caps and some new resistors. Little or no vertical sweep, volume adjustable hum, and no reception. It kills me to have a real nice set with what is supposed to be one of the best performing chassis ever made and I have no luck after a recap. Anyone would at least expect SOME kind of improvement I think. Any help here will be great if there are any Zenith fans in this crowd.

Thanks!!
