Got a pair of JBL L166's at a estate sale priced pretty high.
These are my first pair of "L" series speakers.
There was no way to test them and did a gamble and could end up a costly gamble.
One speaker works perfectly and sound is very punchy. I watched few trailers and was feeling like in a movie hall but another one is little messed up.
One tweeter doesn't work and the woofer surround is unglued from the cone in few areas.
The surround came unglue only after playing few minutes and it doesn't appear to be rotted so re-glue could work.

The tweeter is the big issue.
Any ideas on what to check to figure out if it's the tweeter or if it has any fuse?
Also, is the tweeter unobtainum? There is not a single 066 tweeter in the auction site and ended auctions are horribly expensive. I read that 044 can be used as a replacement but would like to match if possible.
Will it help to clean the tweeter/mid controls?
Looks like I have to take the woofer out to access tweeter and controls.
It's been few weeks but haven't have time to work on it yet.
Thank you for suggestions.
