Beveridge 2SW-II Schematics?

Hi Everyone,
I have a pair of Beveridge 2SW-II's inherited from my father that have been sitting for a couple of decades now.
Id like to bring them back to life and was wondering where I might find a schematic for the amps.
Any information is appreciated.
Let me know if more info is needed to narrow down this search and thanks in advance.

Just tried it, got to the index page. "get in touch" doesn't work, but facebook page does. https://www.facebook.com/BeveridgeAudio so maybe try the FB page.

This is on the page I saw the other day and today---

Beveridge speakers are quite rare, even more rare... documentation. There are some threads that may have some information. If you can post that schematic here, that would be great.

Here is one thread that may have some more information: https://audiokarma.org/forums/index...p-tubed-balanced-input-i-o-schematics.952372/

I have probably made the most posts in the forums on Beveridge models, having had two sets, the Model 3 (still own) and Model 5 (sold in a weak moment). Since I am too lazy to retype it all, here is a post I made in another thread some years ago in 2013 with regard to the 2 SW:

The 2 series used three separate panels and all the owners I have found, thus far, have at least one panel in each speaker that is dead. Plus, they have internal amps that also are a challenge to repair. Only my observation, but all of the Beveridge speaker models were in a constant state of development, so the later the model, the incremental improvement (until it reached the circuit board stat in the Model 5).

Do a search for Blue Shadow as he has a set of them he has been trying to restore for about a year now, I think. He has a thread in the tube forum that will give you some insight into repair challenges.

Having said all that, the Model 2 SW is probably the best overall sounding model Beveridge ever made. His purest model to his original design is the 2, but people ended up adding a sub (s) to their sets to bring up the bottom end like the 2 SW and although I've not heard them, I would imagine they are outstanding. As I started, finding any Beveridge is rare, so having any of them would be quite a nice addition.
 
Amps are now 40 years old replace all the electrolytics.

Good Luck!

Well, its been 2 years now and I haven't had a chance to make any progress on this endeavor.
I think its time I start looking for a buyer that has the time and know how to take care of these properly.
If anyone can recommend a good marketplace, one that is familiar with the value of these speakers, I'd really appreciate any info.
Thanks in advance!
