PostSubject: Philco 96 Speaker Rattle   Fri Oct 15, 2010 6:53 pm

Hello everybody.
I have a Philco 96 radio. You probably know what they are, a BC only Tallboy that has 9 tubes with two 45's in push-pull. This is the one with the speaker that looks like it is made of a burlap sack.
My problem comes with the speaker having an awful rattle. When it is turned up to listening volume, it will rattle to no end. My question is about the screw in the center. The speaker isn't secure to the screw. I noticed that if you push in on the center of the speaker cone until it hits the piece behind it, it won't rattle. The screw is to that piece. Is the screw supposed to hold the speaker cone itself, or is it supposed to be held in some other way? If the speaker cone is supposed to be secured by the screw, I will just get a larger washer and put on the screw, becuase where the old washer is, the speaker has torn out from around it. The rest of the speaker is in great shape, but that is the only problem.
Any help would be great.
Thanks,
Brian.

Yes put a new washer on it and it will get rid of your rattle.

Remember that center screw also allows for centering the voice coil. You will need to do this also. 3 thin strips of a business card or strips of plastic will usually work. Slid down between pole piece and voice coil.

Absolutely. And if not done, two things will happen. Rubbing voice coil that may sound nasty and rubbing voice coil that may eventually wear open. It works...

I haven't noticed any bad sounds from it. When I took the screw out, did that make that piece loose? I will look at it in a bit here.
Thanks for telling me that, that could have been bad.
Thanks,
Brian
