I pulled both of the mica caps that are directly in the circuit and tested them for capacitance and leakage. All of the resistors in the circuit test within their range. I do not believe the oscillator itself is running, as the oscilloscope did not show anything on either the grid or plate of the tube. I suppose the variable caps in the circuit need to be adjusted to get it functioning again? I also swapped out the 6J5 for a spare one to no avail.
