Hi Oscar,
Yes that would be 24 ohms. That seems reasonable. Perhaps I jumped the gun I didn't ask which tube do you connect the antenna to for better reception? I assumed it was the rf amplifier tube but maybe it's the mixer. There are about ten different runs of the 89. The major difference is that the earlier runs use a #36 for the mixer and the later a 39/44 tube. Which is yours?? Does your set have a 36 tube in it? Knowing this it will make it easier to follow along. You can pretend your an electron navigating thru all these parts and coming out of the speaker!
>As you may notice, I know nothing on electronic devices, just love them and would like to hear them playing well
So you have a vom. Do you know which end of a soldering iron not to grab?? This job will probably require some soldering skills, doing some voltage / resistance checks, and maybe rewinding a small section of a coil.

ps 48-482 is no fun to service...

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
