Please show me the fault in this circuit

[hochiphu]

[FONT=Verdana, Arial, Helvetica][FONT=Verdana, Arial, Helvetica]i try to simulate this circuit many time but the Vout of this circuit is Dc,not Ac ,because in fact this circuit is a Hartley circuit which create the sine wave.and can u give me the true value of components of Hartley circuit (absolutely that's work properly),thanks u so much

You are probably after some help with electronics but this forum is electricians'

I'm not sure what you are asking for. Do you want the equivalent circuit driven by an AC source? The AC voltage source would already be a sine wave.

put some JAM on it, it might work

Thats scary.

It's a standard circuit for creating a sine wave (but it IS for DC!!!).

If the outputs are registering DC, then you either have no feedback or insufficient to start and/or maintain the oscillation. The first step is to check the connections of the tank feedback circuit from collector to the base of the transistor, not forgetting the essential ground connection to the tank coils.
It would appear as if you have a tank circuit of 2 x 750uH in parallel with 150uF, if this is the case you may have difficulty starting the oscillation let alone maintain it as the calculated resonant frequency is a bit low at 335Hz. The series fed hartley oscillator is at its best resonating in the KHz region. Therefore, a capacitance in the range 15uF to 150nF would be much more likely to work, the calculated resonant frequencies will then be between 3.35KHz and 335Khz respectively.
If you want further help with this please post a better copy of the circuit diagram as its almost impossible to decipher the component values.
