|I flipped them over. The smaller is on bottom and we can't see the step. Notice the writing doesn't show on either side. if it did my parts would not be match properly.
That solder job just about licked me.
I just laid the leaded JFETs face to face and made the center connection the positive lead. Check with the ohmmeter and find a low reading to the center pin. (about 40 ohms.) Spare that connection. The remaining connection is the Negative lead. Put it in series with a coil and a 3 volt supply and it sings.
