PostSubject: Help with speaker re-cone   May 2nd 2013, 8:27 pm

Hey guys,

I've been repairing antique radios for many years.
I have always sent out the speakers for repairs.

Well, the time has come to try one myself. Shocked

My latest project is a Philco 38-62 Console.
About 40% of the cone is missing.

I have a few questions:

1) How difficult is replacing the cone?
2) Where can I get one?
3) There is a screw thru the center of the spider, is this some kind of adjustment?

I did check for continuity of the field and voice coils. Everything seems fine with both coils.

thanks for your help,
Jose

That depends on your willingness and time to tackle that item, it can be fast and simple by replacement.

2) Where can I get one?

a- You could post ad want ad in our forum or on the web.
b- you can also cannibalize a PM speaker of the same size it looks like a 5 or 6 inch speaker and just mount the field coil and use the PM speaker,
c- or remove the pm speaker cone and glue over the left over tattered speaker.


3) There is a screw through the center of the spider, is this some kind of adjustment?

That is used to center the spider which controls speaker cone centering.

I did check for continuity of the field and voice coils. Everything seems fine with both coils.

Note you should see the schematic also shows a hum bucking coil which will have to be considered. that may be eliminated and possibly replaced by additional power supply cap.

thanks for your help,
Jose
