Dr. Brown's AR2s

Great pictures Roy, thank you!

Thanks LouB, I'll double-check that. Would you recommend cutting the dust cap to see if the voice coil is properly centered or has any debris around it?

I have a woofer rattle in one of my mid-60's AR2s. I've pulled the woofer from the cabinet to make sure it's not something in the cabinet and I still get a rattle. I've inspected the woofer basket, surrounds and the spider and it all looks good...nothing loose, no tears, no much deterioration that I can see. Do I need to cut the dust cap and peel it back some to inspect the voice coil? Any other suggestions? Thanks!
