60 MB restoration
#32

Spent tonight repairing a pair of speakers.

Here's the one that came with the 60MB. It had been re-coned ages ago and the glue failed on both he surround and spider. It still sounded OK until the volume was really cranked up when it would started buzzing badly. I spread some Aleene's clear gel tacky glue around and will let it set up over night.

I also tackled the speaker that came with the parts chassis. The cone was completely trashed and the spider damaged but useable I think.

I cleaned off the glue residue with Acetone and used a little Naval jelly on the frame. Some Boeshield T-9 should keep the rust at bay.

The new cone came from MAT Electronics. I just had to trim about 1/16" around the rim and slightly enlarge the VC hole. The foam surround does stick up a bit beyond the frame edge so I'll probably have to use some shims

I'll fire them up again tomorrow and use whichever sounds better in this set.
