Need help identifying and getting replacement parts

As the title states, I am looking for replacement parts for these 3 guys in the pictures. I’m guessing by the designation that they are Inductors, but I don’t have any experience in replacing these as I haven’t had to up to this point in my career. Any and all help is greatly appreciated. The corrosion on them is why I am wanting to replace them at this time while I am working on this board. It’s to an old Zenith Sentry 2 tv that a friend has asked me to take a look at.

Here are the 3 components

Designation L1209

Designation L1211

Designation L1213

Hello jbwafford,

Yes, the L designation is universal for inductor.

Sorry, I’m unable to find anything close in DigiKey’s offerings.

Perhaps you will get lucky and the TV set will function after you complete the repairs. It’s possible that the corrosion is limited to the surface.

My fear is that you are 20 years too late in your attempt to repair this TV set. I would recommend you locate a second set from which to take parts, but that is nearly impossible to find. When we shifted to digital TV in 2009 the vast majority of these analog sets were cast to the curb. Ironically, you may have better luck finding a black and white 1950s vacuum tube TV set as these has a small following with collectors.

Best Wishes,


P.S. I like the idea of a retro space. Connect a game of pong and we can teleport back to the 1970s. Assuming this is a larger set, you may be able to install a modern flat screen into the cabinet. It won’t have the same feel as the old set but it could be convincing.

Thanks APDahlen, hopefully it is just surface corrosion, but I was hoping there would be an alternative part available. I like to be thorough in my refurbishments and have been doing my best to learn as much as I can over the last year. I’ll keep moving forward with everything that I can and see where it all ends up. Hopefully I can get a few more years of life out of this tube before it has to be permanently junked.

Hi @jbwafford ,
It is somewhat unlikely that the adjustable coils/baluns are the first ones to fail in a corrosive environment. As the PCB seems to be a cheap one layer type, I’d first go through all the solder joints on the (bottom side of the) board. Corrosion strikes first there. Apply some flux on each suspicious joint and use a soldering iron to iron out the fatigue.
