SDA's tweeters dead

deceiver

Hi, I recently fired up a pair of SDA2's. Or at least I think they are that model. Woofer, three midrange and two tweeters in each speaker. I purchased them new in the late 80's/early 90's. Because of a move they hadn't been fired up for a couple of years. They sound great but I noticed that I don't have any sound from the tweeters. I remember you could brush your finger over them and they'd tickle. Now it seems they're dead. I know from the forums that I should do an upgrade on them but, I'd like to get them working first. Is there some kind of tweeter fuse or cutout? They (the tweeters) don't work at all, in either speaker right from power up.
BTW.. I purchased them at a time when there was only one store in Maine that carried Polk stuff in Bangor Maine.
Thanks.
