RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

My Hobby Website:
A few days ago, Mr. Tim O. sent me photos of the Crosley model 03CB console (floor) radio his mother owns and which he remembers listening to as a kid. Tim says as far as he knows the radio still works. As can be seen in the images below, it is still in pretty good condition for a 75-year-old radio. Maybe the reason is because, as Tim says, "Not perfect, but if we touched it growing up we got in trouble." LOL! If my 03CB had been in that condition, I would not have bothered stripping it down for a total refinish job.
I noticed that both the volume and tuning knobs appear to be a bit melted, which must have been a common occurrence in this model because the Crosley 03CB radio that I recently bought and restored also had melted volume and tuning knobs. The metal chassis must have gotten extremely hot to cause that, with the heat being conducted to the metal shafts. It is unlikely that the volume control potentiometer got hot enough to melt its knob, and the tuning shaft is connected to a flywheel with dial cord running around it, so no heat is generated there. Fortunately, I was able to buy a set of remanufactured inner and outer knobs for mine.
Thanks to Tim for providing these pictures.
