Hi all - I just picked up a pair of Altec 890A's with the 3000G horn tweeters. The drivers are in great shape but cabinets had a few scratches on top. So...one speaker worked great, and with working Lpad. No tweeter output in the other speaker. So, I pulled the passive radiator on that one, and connected the speaker wire (with no bass, and just treble) directly to the tweeter leads, and viola, they do work. So, I will try to DeOxit the Lpad this weekend, but if that doesn't work, what should my next steps be? Should I replace the capacitors? (one looked like a poly cap, and the other shaped like the orange drop cap) Any suggestion is appreciated. Thanks. And I was awed by the size of the magnet on the woofer!!!
