I've been trying to find someone who can repair a vintage RCA driver for a friend. One of the drivers is in perfect working order. The other driver when the tech pulled the diaphragm out of the driver the VC was stuck and came apart. However the diaphragm was left intact. The VC just came away.

There are no replacements diaphragms for this driver and if possible the owner would like to repair. Is there someone out there who can wind a new VC and attach it to the diphragm? We have one working model to work from and remnants of the original VC. I know this would be tedious work but the owner knows he won't find another driver or diaphragm.

thanks
