A7 cabinets and glue question

**tinpan** · November 20th, 2011, 10:33 AM

Hello,

What a very nice forum to find. I love vintage speakers

After listening to a buddy's A7s and prodding from another buddy, I ended up getting a pair of A7s last July. I noticed the other day that the glue on the top panels seems to be separating. I really like the original finish on these cabinets and don't really want to have to take them apart for fear of further damaging the finish.

What would be the proper way to fix this or should I leave it alone?

Here is one speaker

Another angle

Here is the other speaker. I'm not really sure if these are coming apart or if I am just noticing this.

I did replace the butchered port boards on the front and replaced the cut up grill cloth with this black cloth

Other than that they are quite nice.

I hope you don't mind lots of pics

Thanks

Tinpan

crud...it looks like we'll have to wait three days for me to post the pics. Anyway...

Edit - 3 days later and pics

You can upload your pics to a photo hosting site like Photobucket,Flickr,picassa,image shack,etc... and just copy & paste the [IMG] code into your post and it will post your photos.

The plywood is delaminating? Or is it MDF swelling? Or are they the 'Magnifient' furniture version?

Welcome to the board !

I noticed the other day that the glue on the top panels seems to be separating.

Not good ! Seperating, I will guess plywood.Depending on the damage if it is just starting I would try to get a bunch of Titebond wood glue down in between the ply's and clamp it.

However if it is real bad, new cabs would be in order IMHO ! They will resonate like crazy with all the ply's flapping in the breeze !

If it is a seam separating, you could use one of these injectors (or similar) and inject from the inside of the joint. Clamp the heck out of it and, after the glue sets, caulk the joint with a construction adhesive (PL400, etc.). After this treatment, there will be little worry about the joint separating.

Holy $%!^ Whatever happened to the $1 plastic syringe?

That might do the trick. If I can find a long enough clamp I might be able to get enough glue in there to hold it down.

I can't post a hyperlink which is where my pics are.

Let's see if this will work. Page 34 and 35 are where the four pics are

ok that didn't work, I'm still in the 3 day penalty box

Oh yeah, it's the top seam that is seperating

That is what I still use but maybe it is going the way of $1/loaf bread, $10K cars, and cheap bluejeans.

The last time I asked a pharmacist for a big syringe like these he was quite reluctant, at first. After a bit of conversation he probably realized I was just another crazy old skinflint and gave me one.
