Are you asking which coil is (7)? If so, merely look at the link in my previous post. (2) is the antenna coil, (7) the first RF coil, (10) the second RF coil.

When you are measuring between the grid and ground, you are measuring the continuity of the coil's secondary. It is important that you measure between the plate and B+ - in other words, what I asked you to measure in my previous post. I asked this because it is usually the primary of these coils that is prone to failure.
