Hello all! I don't really care on old or how long does this thread been "frozen" someone might find this information useful.
I recently got my hands on a pair of this lovely speakers that were on a very bad shape (I've seen them in a bad state about 10yrs ago...)
I needed to replace the foam surrounds, the tweeter pot is not helping out. the 6uF crossover capacitor measures perfect but has corrosion marks. I can't really make up if its leaking.
little did I know, a lot of moisture got a hold on those woofers. even one screw terminals was completely isolated. when I got to work on the foam surrounds, both voice coils were corroded solid onto the magnet assembly... the magnet was also badly corroded and separating: made the job longer but easier to clean. I don't really know how but I did make the woofer reconstruction possible, cleaned the tweeter pot and finally had a listen to one speaker (one half way finished)
I love them now. I have a few speakers... modern and classic. these ones sound confy.
I'm posting pictures on the work that I've done. I wont make a how to since I could have made better moves on this.
the only foam surrounds that I found (similar to the original ones) don't look as "clean" but I rather have them working.
I've had to dismantle the spider from the basked. that was the worst part. had to use heat and a scraper tool. after all parts were free had a 4H cleanup job of everything.
then, redo all parts, with blood, no seat and no tears (the woofers work!)
so: Don't give up on old equipment. now: I'm hunting for new pots and maybe capacitors just to be safe about it.
(Edit: Typo, smelling glue did not help)
