Oscillator coil
#1

I have a Philco 37-84, which has a bad oscillator coil. I need a 455, however I have found these 456 on ebay. Would either of these work for my radio? I am new to the radio world, so all help is appreciated.

thanks!

I always rewind the bad ones I find, but I would wonder it there is even room for the first one. The second one looks more like a Philco coil, but that is not advice to purchase it.

I have never rewound one. I do still have the old one though. Thanks for the input!

understand that coil itself is NOT what dictates the frequency, it is when it is coupled with your particular capacitor, then it forms the tank you have and it resonates and this is then what your oscillator produces as the frequency.
Different radios will thus used different tuning caps and different coils to produce the same IF.

You can look at your existing coil and see if it is similar in geometry to what this one is.
But ideally you should take your coil, count the turns (which are not many) and rewind it.

PK +1 for the comment above. The universal, has a slug to tune it for your application. If you wish to have it original a rewind is the best option. My eyes are not up to it so I have it done by our own Ron R. He does a nice job and has better eyes (apparently) than I do. Not certain if he does ones this new and can't seem to find a link to his offering. My problem being computer dumb.

Rewind the old one. It's simple and cheap. Just need some fine magnet wire. The part that is bad is the small winding near the bottom of the coil. Remove it and replace it with 25 turns magnet wire. Original was 38 gauge but isn't very critical. But the direction is must be wound in the same direction.

Yeah, smack an old wall wart apart for some stock.

Thanks for the advice!
