If you look at just the resistance you would think that the secondary is longer than the primary because it has more resistance. But I know that the secondary only needs to be about 20 percent of the primary for the oscillator to run properly. So the secondary must be wound with small gauge wire or the resistance measurements are wrong.
So is the suggestion to remove much of the secondary wire because it's longer than the primary at this point? If so how many turns? I have about 140 turns right now on the secondary. If so, why does the schem have quite a bit higher resistance measure for the secondary over the primary? I know about inductance but there must be a formula or something to calculate that. Sorry I'm not very "electrical." I'm more eclectic.
