Zenith porthole 12" console

[Adam]

Now that I finished with that newer Zenith, I'm back trying to fix this one...

I poked around with the scope and didn't see any video or audio signal anywhere. Then what I tried was to set just a regular signal generator (with the AF modulation on) to the IF frequency, then hook it into the grid of the 1st audio and 1st video IF tubes, just to see if a signal would get through. And it did, I got buzzing in the audio, and those lines on the screen.

But the problem still turned out to be not in the tuner, but in getting power to the tuner. That choke coil I circled, L19 is open. What can I replace this with? All I have is the Zenith part number S-15128 and 1.5ohms, it doesn't give me the inductance, or any equivalent part numbers.
