Rusty 802-8G

With some good cleaning and some work with a wire brush, I actually got it working!

I used some WD 40 extensively, and a thin razor blade to clean out the gap. I then used some paper speaker shims and compressed air to clean it out even more. I then used a wire brush to clean the rust off of the plate. Here are some before and after pictures:

I installed a diaphragm and hooked it up and got good sound out of it. I had another standalone 802-8G and hooked it up (both outside of the speaker box) and they sounded about the same. Definitely not a final test but getting closer to potentially saving this driver.

Question: do you think that I should still use the Evapo-rust?

If the gap is rust free you can probably skip it.

Did you clean all the WD40 off, and out of the gap? I'd probably clean it with soap and water and then blow it out with air....... or maybe alcohol (the 90+% stuff) in the gap, and then blow that out with air.

Disclaimer...... I've never worked on a HF driver, I'm just tell you how I would approach it, given my experience in cleaning other things.

WOW! Great work!

I am impressed. I think you may have salvaged it after all, at least good enough for a working spare. That looks a LOT better than i would have expected, especially in the gap. I was really afraid the oxidation would have eaten away some of the edge of the crown on the polepiece.

That said, i still couldn't sleep at night knowing it was bolted to one of my horns. It'd have to find a new home.

Liquid metal-filler(available in small tubes) and some fine sanding would make those pits disappear. Use JB Weld if you need more toughness. Great job.

If you say it sounds as good as your other ones I wouldn't F with it just run it.

Good job! I have an old driver in similar shape that I may try to clean now. I'm curious how you got the phase plug out and what you used to reattach it?
