Curt55 Posted August 22, 2018 Report Share Posted August 22, 2018 Hi all, I am a new member but have been lurking recently. I am about to get behind the AR1 woofer and replace the cap with a Solon PB 24UF and the rheostat. The rheostats I plan to use are military aircraft surplus 17 ohm 50 watt. They came in a sealed aluminum clad bag with desiccant and a colored dot indicator that reacted to the humidity slowly after I opened the bag. Very cool I thought. They were packaged in 1960. Here is a photo of one woofer and 755. I have a questions about the woofer. Do you think the surround needs more goo ( is that the correct term). When I depress the cone rebounds slowly and takes about 2 seconds. I have been successful in the past with newer drivers using a slight vacuum to repair dust caps, and dome tweeters. Should I try that or leave well enough alone. It looks like it is going to be a bear to release the woofer from the sealant, slow and careful I will go. Electrical duct seal is what I plan to use for re bedding. Here are some photos Quote Link to comment Share on other sites More sharing options...
