[QUOTE="electricroo, post: 8331945, member: 663793"] Ok, I realize this is an old thread, and yes I was just trolling the net and found this topic. But I have been searching for a schematic for those old mind blower speakers. I remember that the circuit was comprised of an input transformer, darlington transistors, and an output transformer mounted on an aluminum heat-sink bolted to the speaker magnet. Yes the simple darlington circuit coupled with the transformers were their secret. I would like to reproduce them. And yes they were clean. Had them in my 69 Roadrunner. When I killed that the speaker cones dry rotted sitting in the basement. So I removed the amp cahssis from the speakers and installed them on a better quality tri-axal set of 6x9's and stuck them in my 79 blazer. They even sounded better with a higher quality speaker. If anyone comes a cross these, even taking the plastic cover off and sending me detailed close up photos would be helpful, or even a broken set would be better.
