I don't know, sorry, I do know I would never have one again----at least like those I have had, which by the way were the only autos I ever saw. Supposedly only the L-78's and LS6's had them???
I bet a convertor place would know what they could do with one, they have certainly got that process down today. Probably childs play to them, the only difference being they have a much larger case to work with than their current 8-9" jobs. Again, going by mine, they couldn't make it worse
I think alot of their wizardry regards the small case with less mass, and a firm lockup regardless of stall, but I really have no idea

Surely they could adapt that stuff into a large case and only lose the different relationship to volume/mass?
