I recently acquired a Philco 46-480 radio which I'm in the process of restoring. The band switch on this set is labled as:
P.B.
B.C. (broad cast)
SW (short wave)
FM (broadcast FM)
Can anyone identify what the "P.B." stands for? Also, are the preset switches for any particular station? If anyone has a user manual for this set that would be helpful as well.
Thanks in advance for your help,
Regards,
Pete

On your radio , the PB stands for push buttons. there are 6 of them. Originally there was an instruction s that came with the radio and it told you how to set up the push buttons.
Basically you would set the radio to AM, or possible BC. AM is amplitude modulation and BC is Broadcast band. They both mean the same thing. Then you would tune in a station, and depending on the radio,the instructions might tell you to turn the dial to PB and make the appropriate adjustments on the back of the chassis,,,,
,or on some models you would pull out the push button and adjust the actual shaft by loosening and setting the station , and then tightening the shaft by rotating it.
There were quite a few various methods of setting up the push buttons,
depending on the make and model.
Turning the dial to push buttons just directs the signal to each button which can be set to the station you desire.
If you set one push button to a certain station in your area and mover to radio across the country where there was no station at that portion of the dial you would get no signal and the push button would have to be readjusted
You do not want to play your radio until the capacitors have been changed,as it can damage the transformer and they are not easy to find replacements
See if you can contact some one in your area w3ho can do the necessary restoration of the chassis.
you can try the '' Philco Phorum''[spelling is correct'', or '' the Antique radio forum'', and ask them if they know anyone in your area who might help you
By the way , your radio has the OLD FM which is not longer in use [1946 is the year of your radio.
Maybe I gave you too much information, but i don't think so

Here is a link to the schematics.
I have one very similar to the one posted. Not restored but in pretty good condition. Would anyone know how much it might be worth?
