That is the way it kind of was going for me for a brief amount of time. Sometimes it would only tune in stations with the pushbuttons, next time it would only work by manually tuning it. What it boiled down to was DEFINATELY that oscillator coil (for me anyway). The stranded wires went over the top of the coil form (quite tightly) and was attached to that single hair wire in the center of the form. When I touched it with my insulated prod, it bridged the gap and functioned normally. Fixed it as stated earlier. Hopefully your fix will be as easy as mine was. Luck be with you!
