motorola 19k2

I am currently working on a 1950 Motorola set for my boss's wife....seems she loves antiques and Turner classic!
I heard she is excited to have an old tv playing old shows...ok cool!
This set has been difficult and so far I have avoided posting any questions in an attempt to force myself to learn diagnostic tools.
So far so good?
Yes ..the question is there on purpose!
really so far I am fine, I have raster and hiss from the speaker but hooked to a vcr no picture or sound from the show
I did find a cathode choke that shows open from pin 8 of the 12at7 to ground in the tuner.
Being that it is the Osc. side of that tube I feel that this is at least part of the problem.
I realize I may have other issues once the signal actually makes it through the set!
I have a spare tuner for parts but it's chokes are .2 ohm's per diagram.
The Motorola cathode choke is 2 ohm's . Is that close enough?
Fair radio has a selection of wire wound chokes and I believe they have 2 ohm chokes......But are they universal or designed to "choke" certain frequencies?
