Leaky paper capacitors and drifted carbon composition resistors plague this circuit so if after following the above you cannot achieve the correct frequency, check the components and the tube (especially if the resistors and capacitors have not been checked already!)

Sams mentions shorting out a coil in the setup section. I don't have it in front of me but I'll check when I get home. So if I get the wave to look right on the scope and set it around 20microseconds I should be right at that 15.7khz goal?
Sorry for all the questions I'm trying to learn....
