This is what you start out with if you are new to the Technology. At the same time I am pointing out to you a mistake I made out of slow comprehension. Since the 2N3055 tophat transistors have only two terminals "base" and "emmiter" the mounting base "power in" is also the collector terminal, I got into the habit by placing the coil power- strands to the heat sink which is the collector and case of the 2N3005. Consequently when I moved on to the BD243C I connected to the heatsink instead the proper transistor collector terminal. Interestingly I haven't noticed much difference even when it comes to soldering the strand to the proper transistor terminal, Image 6 Bedini/Cole circuit! Image 8 is a different story, this is the SSG icehouse set up. Having 6 strands in my SSG's coils, I took the coil wire return off of the heat sink (collector plate) and took 5 of the individual strands (see Christmas bulbs in my replication 2 page) and soldered them behind the 1N4007 at the collector terminal of the MJL21194's which improved the pressure into the batteries but not necessarily the charging rate. To blow out of the water what i just said, my latest tests with my newest SSG revealed better performance by mounting all six wire strands to the heat sink. Pulsing caps is obviously the answer. In my way you are not restricted to an equal number of transistors used per coil strands. Rather the more branches you create (more transistors in parallel) the more aether radiant energy is being captured, but independently of the strands, sucked up by each transistor mounting plate from the heat sink. Needless to say by using transistor pads and grease you are restricting the aether radiant accumulating process potential.
