Philco Model 116B Tombstone Broken Off Speaker Wires - Guest - 07-05-2010
Hello to all since I am a new member. I just picked up a Philco model 116B tombstone. I am going to restore it. The first thin that has to be done after I have already checked all its tubes and have replaced its filter caps is fix the broken speaker wires on it. I have the radios schematic but it does not show colors of the wire for this radio. Where the wires are off from is the small transformer that is on the bracket on the speaker. All four of the wires are off the four terminals of the transformer. They are the original wires so I know the color of the cloth has faded with age. What they look like to me is white, yellow (?), black with red tracer (?), and a solid red which now looks like a very faded orange. The transformer is good itself. Any help of getting these four wires back in the correct order on the transformers four terminals would help me a lot. Thank you Dave

Hello Terry:
Thank you for your replying back to my post. I do have some photos taken of my 116B with the broken speaker wires and the speaker mounted transformer where the wires are to connect to. But I can't seem to find how to attach photos on this site. I did go to the user control panel seection then attachments but there is no explanatuin where the software is if there is any. So can you email me privatly off site and I can email you the photos to you? n2tjq AT hotmail DOT com Thank you so much Dave

I have a model 116B that I had made a previous post about needing help with the speaker nwire harbess being broken off from the transformer on its speaker. I have now with this post uploaded two photos which I hope that you can see my problem and can tell me which wires go to which posts on the transformer.

Hi Dave
Sorry to take so long to get back have had some computer troubles. As for your Philco It's an easy puzzle to solve. First use some masking tape to mark the wires that exit the chaiss as to where they came from. Should have 4 wires. One will go to one of the #42 tubes in the output stage. One will go to the other # 42 in the output stage. One will go to # 101 which is a 8ufd filter cap and finally one is going to the junction of resistor #94 and a 3ufd filter cap #80.
On the speaker you are going to have five connections. The primary of the output transformer will have three. The beginning of the winding, the center tap, and the end of the winding. The other two connections are the field coil. One of the wire from the field coil is going to be connected to the center tap of the transformer.
So first wire that comes from one of the 42 tubes will go to the beginning of the output transformer. (Doesn't matter which 42)
Second wire comes from the other 42 tube and goes to the end of the output transformer.
Third wire comes from p# 101 the 8ufd filter cap it goes to the junction of the field coil and the center tap on the output transformer.
Fourth wire comes from the junction of p#94 and the 3 ufd cap p#80. It will go to the wire from the field coil. (Not the one hooked to the output transformer.)
See how easy it is!
Hope this answers your question
