Hey,

Thread about M70 began here: https://forum.beoworld.org/forums/t/34886.aspx  . To not mix in threads I decided to put it here.

I bought my Beovox M70 , I did not expect much from the state though they played nice. After buying and the first hours in the house spent listening, I decided to look at them more. They are from one pair (matching serial numbers)

 

The boxes are not damaged :

Speakers and suspensions look good without abrasions, dents and holes in the paper:

The grilles are whole and not broken, although they have small abrasions on one:

and inside....

Crossovers - no repairs, no visible signs of damage, both the same:

SEAS woofers looks like new, with no problem with terminals:


The same with Peerless uniphase - without problem with magnets.

 

Now, after these few photos I have questions:

- whether recap is necessary in crossovers ??

- is there any canvas that was covered with grills M70 ?? I only have a new stretchy acoustic material, in Infinity it looked like the original but here it is different and I do not know what the final effect will be.

- whether the acoustic parameters of the box do not change after the insertion of modern cable terminals with latches or screws?

- how to mount the grills, now they are fastened with self-adhesive Velcro, but you can see it and it is not perfect ??

Thanks. 

In addition to the sound and appearance, there is one more important reason for the renovation.

M70 in the living room gave an unpleasant odor in the air. Confusion of the old basement with the composition of waste paper. Like a warehouse with old, damaged books.

To eliminate it, I had to replace the filling, vacuum the inside of the boxes, change the material for the grill, beeswax gave the whole a pleasant natural aroma.

I finished renovation of my KEF 104aB, ( yes I know it's B&O forum ) here is short view:

I bought it after reveneer

:

I made grilles because I bought without it

and I changed everything inside, all cables, resistors ( 1% tolerance ) and caps ( Solen 2% tolerance )

 

I wrote about it because the point is not to catch the bunny but to chase him so I bought ...

... " Beovox M70... one more time "

I start at beginning with veneer, textile grills, and this time I will rebuild crossovers.

 

I know, I'm little boring but if you want, I will put here photos from my work.

three two one start:

 

My new M70 serial numbers:

 

I started from box. Veneer was scratched, decolorized with spots.

 

Yesterday I put a "rosewood" mask on the surface

and polished it

 

After that it was ready to apply the first layer of oil to draw the color of rosewood

Now it is wet and very contrasting, it looks natural after drying. I will show it tomorrow after the second layer and dry.

Very nice.  When you say you put a "rosewood" mask on prior to polishing can you elaborate on that?  What product did you use and how does it work?

Thanks

My English is so poor :)

I used this to fill scratches and holes in the wood.  It is a special paste with real wood flour and natural coloring resins.

You have no reason to be jealous ... but when it will be finished Big Smile

Your post doesn't have a picture or a link to the product you referenced.  Can you please post it again?
No problem about your English :-).  
I hope the paste is a product I can find here in the USA. I would like to try it on a couple of my projects.

Thanks

Now I used local product from Poland. In USA you can buy "kiełbasa" i "pierogi" from Poland but not this paste. 

Maybe you can find this Italian product, it's the same, I used it too. 

https://www.veleca.it/stuccolegno.html

or you can ask some carpenter

Haha, yeah, foods you can buy here.

The woodworking paste is interesting. It doesn't appear to be available here and I haven't found an equivalent product yet....but will keep looking.

Thanks,

I can buy this Italian paste here and send to you to USA. It's about 10 $ for paste ( 250g ) and 10 $ for shiping ( Global Express ). It is not a TNT and I think that my post office take it to Texas, I can ask tomorow.

First layer is dry,

my wife asleep in badroom... I can safely put second layer ( on table in saloon )

Ok.

You must choose a color Smile

In the meantime, I fixed the broken grill

 

Now, I ordered Monacor sound transparency textile and frame dowels to finish textile front.
