Non Common Ground cable

Would anyone know how much a Non Common Ground Amplifier Interface cable goes for. I got it when I bought my second pair of SRS 1.2tl's. The cable was cut at the posts inside the box because the guy decided he didn't want the interface and used the cable excluding the box. He put the wire together and used electical tape to put the cable together. All the cable would need is to be resoldered to the box. I know they go for good money on ebay in normal condition. Anybody have an idea what I should ask for this. I have no use for it. Thanks for any input.

    There was no reason that he couldn't have used the AI-1 with a common ground amp.

    Anyway, the box without the original Polk pin/blade cable.....hmmmm, never seen one for sale that way.

    Funny.

    I am RIGHT NOW looking for "some kind" of AI-1; to be used to further my experiments in modifying the SDA 1B for use with balanced monoblock amplifiers; and I can't use the OEM blade/pin connectors anyway, since I have blade/blade sockets on the speakers.

    Just yesterday I had my first trials with a single-conductor (blade/pin style) SDA cable; and while the results were not all I hoped for, (not enough volume with the single-conductor cable--the SDA effect is weak) it does seem to be do-able electrically if not sonically based on a comparison of SDA 1C vs. 1B schematics. My next steps will be 1) put an isolation transformer into the single-conductor SDA cable; and 2) bypass the SDA capacitors in series with the SDA signal in a desperate attempt to gain some SDA volume.

    I just finished reading the Parts Express estimate for the Big Doggie "Dreadnaught" transformer--Not in stock, can be "special ordered" and will cost $130 plus shipping and handling. That's not in the budget for awhile.

    F1nut are you saying if I put original cable back together with the box I would be able to use a common or non common ground amp. If so maybe I will just solder it back together and have some flexability with my system. Is a non common mono block amp the same as a bridged amp. I have two Luxman M-117 amps that I can switch to bridged easily. Would that work with this cable?
