Hi there,
I think you have my Email Lew. This is a stereo amp. I did not know how I would like it. I elected to minimize the investment, after all these are 30year old speakers. One bad panel and these are expensive planters.
These are robustly built and I really don't know how much better the separation et al would be in mono in this form factor. I also elected to keep the chassis a simple Bud box to minimize cost in case it did not work out.
These are completely tube input and driver.
The main advantage of mono of course - and it is a nice one- is that you can have extremely short polarizing runs to each speaker which is definitely what I'd like to do, keep things neat and gain , theoretically, better separation. Weight plays no factor in this amp so no mono advantage there. I am not missing much with the stereo.
All that said it sounds really nice now and I was running a $13K amp on them with my front end many multiples of that.
The Beveridges were a diversion and they turned out to be almost as incredible in today s advanced world as the were more than 30 years ago. They will be staying around for a little while longer
I have plans to change the caps ( already in house) and if I get time will do that this weekend. Roger offered to install what I wanted, I elected to wait and hear it before I invested $5-600 in caps for it.
I made the investment in the caps :)

I bought my 2SWs completely on a lark, just "because". I wanted only to have the experience of hearing them and then thought I would pass them on to someone else of a similar level of craziness. But now I am addicted; I would never let them go. It took some experimentation, pain, and frustration to get them just right, but now I love them. Best of all, I can stay up all night listening to them, if work obligations permit, because my wife is oblivious to them; she cannot hear them at all in our bedroom, two floors above. Whereas, my big Sound Lab speakers are in the living room right below our bedroom; they must be turned off by 11:30, most nights, or I have a domestic dispute on my hands.Incidentally, the panels are very long-lived if not mistreated by a blowup of an amplifier, I think because they do not carry a quiescent charge. I bought a roll of aluminized mylar, which is what you need for rebuilding a panel, should the need arise. It's still available commercially, but I would advise stockpiling some, just in the rare case.
PS. Is that the (stereo) direct-drive amplifier, sitting down on the lower left in your equipment module? My only thought is not about stereo separation or any other niceties of monoblocks; it's more about the length of the speaker wires. They would need to be quite long and very well insulated.
Marantz 10B. Very very cool.
