Did you ever find a source for a fix of your Symmetry xover? I have an ACS-1 that went south on me many years ago and I contacted John Curl, the designer. At that time he sent me a service manual for the ACS-2 that also covered the ACS-1. It is a poor FAX copy, but useful. If you are interested, I can make a copy and send it to you. I don't know how it will copy. I am looking for parts myself. If you hear of any sources, let me know. I read a post from John last year where he said he had some parts. If you want to unload your unit, let me know.
