Hmmm, It doesn't look like it! With the cct not oscillating (checked with the scope) Why should there be a + voltage on the gate when there is no connection to +Ve, this voltage is maintained with Rgs=1k Vgs=0.2V,with Rgs=100 ohm Vgs=50mV. Is this normal for Fets? I posted the datasheet for the IRF2807 a few pages back.
