Here is a jfet mixer circuit I am trying to use as a building block for an AM radio. I have built a separate local oscillator circuit that is working fine but the issue is that as soon as I connect it to the mixer circuit, the oscillator stops oscillating down from 3 MHz to zero.

Can anyone please advise what the issue could be ?
