Oops, sorry, I stepped on Ron Ramirez. Sorry, Ron.

George, are you measuring the section of the tuning condenser that goes to the grid of the 1st detector or are you measuring the oscillator section of the tuning condenser? If measuring the grid circuit, yes, you are measuring the secondary of the RF output transformer. If measuring the oscillator section of the tuning condenser, it should read open circuit even if "in circuit", and my immediate previous post applies.

Another Phorum member had a similar issue (dead oscillator) that was caused by leakage in the oscillator circuit of the tuning condenser. Out of circuit, the condenser measured in the 10s of K Ohms between rotor and stator.
