the drivers are 30watt 12" and are set up in a strange series.. two are dual-cones so they have been set up like
single/dual/single/dual in the original cab.
I have been told that the stuff I got (a treblecleff PA system, paid AU$45 for it too ;) is what was being used as stage sound in the late 60's/early 70's by some pretty high profile bands, so it's fairly ancient... solid tho, not tube driven.
I still have one cab intact as well, so there's a potential future project I guess.
