I helped a friend move a few months ago. Amobg his prized possessions was an old Philco floor model radio. He said that it was working at one time but not sure how long ago.
my background is working with guitars and amps. I covered a little "communication" electricity with my basic electronics a few years ago.
I want to help my old pal out and get the beauty working. Here are some of the questions I need answered.
1. The label shows a chassis number "40A" which I beleive is the model number.
The exact model I am not sure and will have to refer to the pictures to find a match.
This unit is listed as 25-40 cycles. As I understand it, the household current is 115 volts at 50-60 cycles. Will this unit work? Is there any modifications to enable me to match the cycle rates?
2. the speaker is in poor shape. As my pal is only looking to have it operable but doesn't want to spend a lot on it, I would propose to replace the speaker with one that I have on hand. I am curious about the connections to the speaker. This unit has a cord with wires running to a 4 pin connecter. These wires appear to connect to the speaker magnet assembly. I looks like some kind of 'tap' coil. There is a lot of movement here.
Also there is a pair of wires coming from thetuner assembly. These have a pair of 'new' wires (lamp cord) attached and continuing on to a 'lug' connector which is also going to the speakers.
At present I do not have any pictures. I will attempt to get some as it may help clearup any confusion.
I have looked at a schematic but was not able to establish what wires are supposed to go where.
the unit has a 10" speaker and the following "specs"
40 Watt, Code 121, CSA 1476, T 1041 (stamped on chassis), cycles 25-40.
Tubes: 7A7E, 7J7E, 7B7E, 7B6, 7B5E(?), 7Y4.
Any help/advise would be appreciated.
