If there is no slug, then the oscillator would be adjusted with the trimmer capacitor screw on the small section of the tuning capacitor. Find a station at the high end of the dial that you know the frequency of. If you tighten the screw 1/8 of a turn, this will move the station up the dial. Turn the dial higher and find it. If you turn the screw out 1/8 of a turn, the station will move down the dial. Continue "walking" the station either up or down the dial, whichever applies in your case, 1/8 turn at a time, until the dial pointer is at the correct frequency.

Each little trimmer cap is in parallel electrically with its tuning capacitor plate section. Together they act as one capacitor. When you tighten a trimmer, its capacity goes up so to keep the same frequency the large cap plates have to open up more, and vice versa.

After you get the stations at the high end of the dial where you want them WRT to the dial markings using the trimmer, then on a weak station around 1400 or so (can be WAY down in the mud weak) peak it for max volume using the trimmer on the other, larger section of the tuning cap, which is the antenna section.

Holy mackerel, it just dawned on me that you rewound an oscillator coil, and made a pretty one per the picture at that. Ain't a whole lot of newbies to tube radios that have done (or would even try) that! That's the fun of this stuff to me: making something out of nothing!
