I got a steal of a deal on a beautiful 690. I have restored a dozen radio's (I know, I'm a Rookie) but nothing prepared me for this monster.
My problem is for some reason two of the oscillator coils got really hot and melted all the wax of the windings. One test good still the other is fried. It is coil 36 on the schematics part number 38-2627.
I have rewound other coil before with success, but it was well documented here and on YouTube. I however can't find any info on this one. I'm hoping someone here might have a clue how to rewind this one. If no one has any info I will try slowly unwinding and trying to figure out how it was wound.
I've had this radio for almost a year and after reading Ron's blog a couple times and going through the posts on that model here I decided I would give it a go.
Thanks for any help you all could give.
I have been reading these phorums for years and have always found the help I needed without having to ask.
