I'm an old hifi guy but have never posted on the internet & have little to no experience with electrostatic speakers. I have a pair of 1+1s that vibrate on certain cds so I was going to sell them "as is" but then I remembered that I have a pair of Final .4 electrostatic panels. I'm wondering if the voltages might be similar enough that I could hook up the Final panels to the Medallion transformers. Any ideas ? Thanks, Ken
The Acoustat panels bias run on 5kv..as for the 1+1 noise....do thay sound like some cds over the panels with bass.....Acoustat are hard to kill...you could have low bias..lose part.....fix for the 1+1 may be low $$...take pic of inside the interfaces.....
post pic...of the .4 panel, wire setup...
Search ....can be the key....ck..Final .4...if you have not ....lot of info here on ESLs

You may be able to remedy the rattling sound on the 1+1's. It is likely because the diaphragm has lost some of its original tension. This is a fairly simple process of using a heatgun to carefully re-shrink the Mylar, a procedure which has been documented many times in these pages.
As far as driving the Finals with the MK121 interfaces, this is certainly possible. The only possible "catches" may be that 1) the Final may not be designed for the roughly 5kV bias voltage provided by the MK121, and 2) the equalization applied by the MK121 may not be perfect for the Finals. In regards to item #1, I suggest you find out what bias voltage the Finals used before trying this set-up. Some ESL's can be damaged by excessive bias voltage. Assuming the bias limits are okay, no harm will come to the interfaces or panels from hooking them up...you just may not like the result.
