From the sound description it seems like the mylar/boPET film has a fairly low level of tension. I'm not sure whether that's through design or just the result of age and useage, though.
It's actually 1200v bias on this version. I think that the 717 will be a bit underpowered driving these things but it's worth the price of the adapter cable.
The mylar is under a pretty low tension in these RTR drivers. Then again they are 1950's technology and design.
