Beveridge Model 3 - Restore

Audio Fan

YT Channel - https://tinyurl.com/29zytwu9
The day is finally here. Since getting them in mid-April, I have been steadily working on getting them going again. Having worked on the Model 5's prior, I was much more comfortable tearing them down and working through each area until finally, tonight, I put them in place for some listening time. And I can honestly, say.... WOW! Being 6.5 feet tall, they absolutely fill the room with sound.

Before I get too far, let me state that I am only in "Phase 1" of listening. After spending so much time on the restore, I'll next start working on fine tuning the listening configuration. I have some external crossovers (a Beveridge model is one of them) that I want to put into the mix, some other amps/pre-amps, etc. so there is much more to come, including getting some external subs. One step at a time...

The next few entries will be some of the restore process so others can benefit if they should happen upon a pair. Also, I need to give a very big THANKS to 24hrez for helping me greatly with all sorts of technical questions as I worked through getting the crossover fixed for the one blowing fuses.

Also, for reference, here is the link to the Model 5 restore thread I started last year. This was my first pair of Beveridge speakers. This thread also has a lot of information about Beveridge and history of the company: http://www.audiokarma.org/forums/showthread.php?t=352331

Day 1 - Below is a pic of the day I brought them home. All the Bev models used a thick foam material for a grill cover. While it worked fine when new, the material disintegrates and falls apart in to small particles over the years. These small bits then find their way into the transducer which I will show you later.

This is a pic of what I found when I opened up the first speaker. This one had water damage and the base was severely damaged, however, it still worked. The other one was blowing fuses and needed trouble shooting.

Years of dust and the top woofer was desperately in need of a refoam.

I decided to mount the crossover on a separate board. This is the dry fit, before I completed the recap.

All new base. The old base was falling apart. I used much better quality plywood to cut out the circle. The trim repair was much more challenging. It is basically a paper tube with a black laminate. I had to carefully cut out the bad section, bend some new fiberboard and glue it in. Then, glue the new trim piece around the new base. It came together very well and is much stronger than the original. You can also see all new caps in this pic.

After refoaming the woofers, time to start with cleaning the transducer. This is, to me, the scariest part since one wrong move and the entire speaker becomes a big conversation piece.

Here is pic of the transducer removed. There are NO pics anywhere, nor any explanation how the two transducers are connected. You cannot see it inside the speaker and I was nervous about pulling them out, but here you can see they are bolted together. As well, you can see the small bits of that old grill foam between the "slats" in the transducer. I used a small natural fiber paint brush and my shop vac to carefully remove all of them from each section. Once done, I put it right back into the cabinet to ensure no accidents (then I could relax again).

As with the Model 5, I decided to use regular speaker fabric to cover the grill. But this time, I decided to use a mesh material. This is a plastic mesh that can be pulled taught and also follows the curve of the acoustic lens.

I initially did not want to use any foam, but to fill in the small gap between the base and the speaker, I ended up using some from the leftovers I had from covering some TimeWindows. I tried some other material, but it was not stiff enough to hold in place with the base installed.

Replacing the old/broken binding posts with much better ones. Also note the connection diagram on the back, this sure would have helped me on the Model 5's if this were posted.

Congratulations on bringing these rare and superb speakers back to life. Looking forward to updates.
 
Here is the first pic of them next to the Model 5. The Model 5's felt large before, but they look VERY small next to the 3's. Once I put everything back together, I spent time fixing up some small chips here and there, then I went over both with some Howard's RAF. That is a LOT of wood!

Very nice job. I'm looking at your table full of tools and realize you were the right guy to do this job on these speakers.
 
Audiofan,

Very impressive resto. I can't say I've every seen a picture of a living room with 2 pair of Beveridge speakers before. You are a lucky man indeed.

PioneerGuy75,

Harold Beveridge built a very small qty electrostatics in his small shop in Santa Barbara, CA. A couple hundred sets in all. Very rare. System 2's were the his favorites where he got his sonic lens really dialed-in, but they were very labor intensive. The 3's were his attempt at making the 2's more practical to produce. I heard the 2's in the mid 70's. They are with out a doubt the speakers I have or ever will hear. Most people that have heard them feel the same way. They do pretty much everything really, really right and most phenomenally the sweet spot is so big, it's not really a sweet spot anymore, yet they don't sound like omni's either. Just amazing.
 
I heard the 2's all weekend at the IHF show in Atlanta. Best I have ever heard even to this day. They are just at another level.
 
Maybe lightening will strike for a third time and I will find some Model 2's??? :thmbsp:

Also, I added a link to the first entry of the Model 5 restore thread to try and make it easy to find Beveridge related info. Sure would have helped me when I was tackling the first set that is for sure.

Very nice. I worked for a guy who had a set of Model 3s, I'm actually drawing a blank trying to think of anything I have heard since that was better...
 
Sweet looking and better sounding. You can rebuild speakers for me anytime.

Sure, drop off some Bevs some time.

Very nice. I worked for a guy who had a set of Model 3s, I'm actually drawing a blank trying to think of anything I have heard since that was better...

They are definitely in a class by themselves. I look forward to trying new gear with them over time and will add updates to this thread.

Also, time to update my avatar with something more appropriate to my setup.
 
Audio Fan....I'm glad I could help. The project looks great!, and it has been a pleasure corresponding with you over the trouble shooting.
 
That's a great story! I believe I've been following along since you found these.
I'd love to hear a pair of those one day.

I have not had an ongoing thread for the Model 3 restore, I believe you are thinking about the long Model 5 thread I started last year perhaps?

Of note, I've spent several more hours this evening listening to various recordings. It just cannot be said enough how wide is the soundstage. No matter if I stand up, sit down, move around, the imaging remains incredible and the clarity is equally enthralling. I started them out facing each other just to see if that positioning were really true and I was pleasantly surprised that they still do image and sound quite nice that way. I then toed them in about 20 degrees and this is where I found it dialed in a little better and have kept them there for tonight.
