I recently had a Philco 60B given to me. I'm pretty competent in modern electronics but I've never restored an antique radio before. This one appears to be in pretty good shape - dusty, but not much rust or corrosion. The antenna and oscillator coils have continuity (nice that the schematic gives actual DC resistance values for these!), as do the power transformer windings, so I figure I've got a good sporting chance.
My first problem, though, is that the speaker cone is trashed. It looks like somebody stuck something thru the grill at some point and ripped out the cloth and speaker both. The field coil, voice coil, and OPT appear to be OK. Is there anybody who re-cones these speakers? Alternatively, is there a source for replacement cones so that I can try to re-cone it myself?
We have Eminence Speaker LLC nearby Louisville. I've purchased drivers directly from them, but I'm not sure if they actually offer any kind of re-coning service like we collectors here need. I'll have to check that out when I get to my 610. If I discover they do, I'll let you know.

Sound remedy did several for me. The last ones were 16 cathedral and 38-690 tweeters, plus they patched the woofer for free when they realized they could not replace 14" cone.
They do not carry 14"-ers. They suggested putting a ring and thenfitting 12" cone but then agreed to patch the existing one and didn't charge me. Did a fne job at that.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
Question related to this thread. If you purchase a new cone to recone a speaker, the voice coil will not match. I have a 37-610 with a bad speaker that needs to be reconed. The voice coil is 1 Ohm, the replacement cones I see have 4 Ohm voice coils. How can you make the replacement cone work?
Thank You Russ,
Makes sense. Shouldn't be too bad with this one. The spider looks fine, I'll have to take it apart to see about the rest. What glue do you recommend to use to glue the voice coil to the new cone?
Which speaker cone do you like? I see you buy them on EBAY. Which seller has one you recommend?
I use white wood glue, like it was contact cement. Apply a little to both surfaces, allow to partly dry prior to joining parts.
The issue with vendors is the changing inventory. Finding cones with paper suspension is much harder than finding ones with foam roll suspension especially in 3", 4" and 5" cones. Be careful not to get a cone with the VC cut-out (center) too large. You can cut a cone that has a VC cut-out that is too small.
