My Forte’s are the later series 1’s with the caps on a square circuit broard. Tweeters dates are 8911, so very late in production?
Based on toxcrudar’s advice, both tweeters measured open with my ohm meter, hope that replacing them will solve the issue. Crites ti’s will arrive tomorrow. I know that I will replace the caps at some point soon, sooner if the new tweeters don’t solve it.
