In Reply to: RE: Save money on Speaker wire Direct Drive- Bevridge posted by AJ on April 29, 2016 at 19:37:21
No, the amp in my equipment rack is the Wyetech Topaz 150lb behemoth SET. This is actually what I used to drive the line sources before the Direct Drive amp arrived. It is quite special.
The pic is "before" the direct drive - my room is a bit of a mess as I have been dropping the Beveridges for the hook up and doing other work so I did not show the current state. The direct drive as shown in the pic sits on the floor right now right in front of my rack. My room is just a little over 17' wide. Thus, I have high voltage silicone wire rated for 5KV as the hook up for the polarizing voltage. I notice no bad effects. At the old Audio Circle site Roger speaks about using his set up in the same way with runs of high voltage test probe wire.
Short runs with monos is safer for sure, and looks better. It doubles the cost. I don't think I would practically notice the difference. Check the link out for the "1/2 Drive" which was an attempt by Beveridge years ago to modify the Model 3's to DD. Roger's effort with me takes a simpler purer input all tube driver approach.
This couldn't be a commercial product unless it was caged and mono. I have no pets and the room is mine so my grown kids don't come down to fuss around and neither does my spouse.
These speakers are the exact same speakers I heard over 30 years ago at a local audio nut's home. I got wind of the sale - they were passed along to someone locally for over 25yrs - and I have them now. The left an impression on me 30years ago and I wanted to try them again - I have not forgotten the first time I heard them. I am glad I have the chance to restore and enjoy them for a while.
I will have to pick up some mylar- where did you get it? My panels look really good no delamination or aluminum erosion.
It seems I actually got the special mylar from RM Labs in Santa Barbara, 3-4 years ago perhaps. This is surprising to me, because I thought I got it from some guy in Ohio. Anyway, the guy in Ohio claims or once claimed to be able to repair the panels, if necessary. I may have found him on the internet by searching on "Beveridge speaker repair" or "ESL repair".
Got it, I will send Roger a note.
There is a guy somewhere in the Midwest that claims , on his website at least, that he can repair the Bev panels. As you know, they are different beast from the other types of ESLs... so who knows. Also there is a Beveridge fanatic in Italy at the "Sound of the Valve" who, if you can read Italian, (google translate is lacking) says that he has perfected the panel repair. He is unresponsive.
Rick Beveridge is a nice guy but I am not sure he is able to do this and based on his situation may never be able to again.
I spoke to Wayne Piquet in Florida earlier this year as I had a set of Quad USA monitor panels into him for repair and he said he would be willing to try to rebuild them... but he has never done it before either.
Wayne's work on the Quad speakers is impeccable. Kent M at electrostatic solutions is unwilling to try.. so if the panels do go it will be interesting to see if they can ever be rebuilt again appropriately. Right now , knock on wood, no need.
I don't know for sure if it's the guy in Italy whom you cite here, but there is some business in Europe that has messed up a few pairs of Beveridges and/or held the vital panels hostage for years before returning them to the respective owners in nonfunctional condition. I think the business was sued. Thankfully, there are a few possible reliable sources of repair work in the USA. As noted, I think I have spoken to a guy in Ohio. It really amounts to finding a guy who can stretch the mylar onto the frame and then re-established the proper circuitry without introducing shorts. On the other hand, if your panels are all well, it's likely they will remain so. Seems most panels have been damaged by bad amplifiers or amplifiers that were hot-rodded by persons who did not understand the circuit.
Yes, I read that post sometime ago whereby a Beveridge owner was had by improper refurbishment of his panels. That outfit was in Germany. The link ,posted, I referred to, is in Italy.
I chatted with Roger briefly and he has the film available on his website for sale. He also mentioned that he "might" be prepared to refurbish panels in the future after his new home base is settled. He has moved from Santa Barbara closer to Berkely
I wonder if Roger himself would be willing if it came down to that. He told me that the Beverages are unique in that both the stator and the panels are driven. Since he has built his own ESL's, it might not be impossible to convince him.
Kent did a very good job on my Stax's, but he knew them well ahead of time. He is probably right to be cautious.
RM Labs in Santa Barbara is, of course, owned by none other than Roger Modjeski. However I think he is no longer in Santa Barbara. He makes his own ESL system now, which seems to be something like the Stax F81's but much more efficient and easier to drive.
Perhaps what you say as regards RM's current location is true; I wouldn't know. As mentioned, I purchased the mylar 3-4 years ago, and, knock wood, I have had no need for it so far. But for sure, AJ knows how to find RM, because he just did business with him, as RM built AJ's new direct-drive amplifiers. And for that same reason, I knew that AJ would know the acronym "RM" refers to Modjeski. Sorry if my response was vague to others.
