Ok Simple enough. You need to know the frequency of the station you what to set the push button for. For instances 630kc for WMAL, 980kc for WRC, 1150kc for WHMC/WJOK, 1500kc for WTOP, 1580kc for WPGC, and 1600 for WINX ( I don't think they are around any more).
Go to pg 63 of the service manual and at the bottom there is a list of the padders. They are in groups of two. One ant (antenna) and one osc (oscillator). All together there are 10 padders which means there are 5 stations can be set which is how many buttons you have not counting the off/on sw.
The ant tunes the antenna circuit in the the radio and matches it to the frequency of the station. The osc tunes the oscillator stage this selects the station noted within the frequency on the chart. Both padder screws when screwed in will be at the lowest part of the frequency range. Conversely when the screw are almost out it will be at the highest part of the frequency range.
To get the hang of it set the band switch to use the push buttons. Push in the 1st button on the left. If that one is the off/on sw push the one next to it. This button should be the one associated with the 1st two padders. These will adjust the ant and osc frequency.
With the set on and working gently screw in the two padder screws #1&2 then back them out about a 1/4 of a turn. Use screw on padder #2 to tune around a little and you may hear a strong local station like WMAL @ 630kc. Adjust screw #1 for loudest signal and your all set for WMAL. If all is well button 1 can be set (aligned) for any station between 540-980kc
The tricky part is that both the ant and the osc adjustments tune fairly sharply so it easy to get one out of range of the other. This means that you have to go back and forth a bit to it tuned in to the station you want. Most of us use a signal generator this makes it easier but I'm assuming you don't have one.
