WTB parts for Zenith tube radio

[Bubba57]

Hello folks, my name is Bubba57. I have been a subscriber in Audiokarma for a while now. But I am new to this Videokarma. I need a little help if you would be so kind. I bought an Zenith X334m at the goodwill and I am trying to clean it up and replace a few caps in it and hopefully get it working. I need a part,,number or source. The part is under the tuner and there are 2 of them. These 2 coils are affixed to a plate that moves in and out with the tuning mechanism. The parts consist of a wrapped coil that moves and an adjustable ferrite rod that. Stays in one position. The rod has a spring and both have red plastic nuts on them. In the schematic the show these to be L2 and L3. They also show 2 different part numbers. L2 is FM RF Zenith p/n S-62887. L3 is FM oscillator Zenith p/n S-64580.

The coils of both of these are good but I have one of the adjustable ferrite pins or rods that has broken off about half way.

Do any of you know where I can find one of these? What is its purpose? And do any of you have one that you could part with?

Any help is highly appreciated.

Thanks
Bubba57

The ferrite changes the effective inductance of the coil. Basically the FM section uses variable coils instead of variable caps to control the frequency settings of the LC tuned circuits.

Thanks Electronic M, where would a fellow get one of these ferrite rod/spring assys?

probably have to cannibalize them out of another similar Zenith radio.

Not a replaced part in the olden days so odds are no NOS parts.
They used the PTO for years so many radios MAY use the same parts.
You may want to get an identical chassis & rebuild that one
to save moving things. Also alignment is tricky on them.
When they work they are better than cap tuned radios but
drove up the price.

Well I appreciate everyone responding to this. You all are right, I probably should just look for a parts unit.

Thanks again
