Hi, I'm new to this forum and Interested in this SG Radiant Oscillator (solid state). I have been redoing circuitry for over few months and learned how to generate this radiant pulse, some success and most failure. recently I have done an 8-Coil #24 @ 69M (226 ft) parallel wound and 1 trigger which is longer #28 80M aprox. at first I could not get it to self oscillate as MJE13009 is hard to saturate so I thought of placing my used 2N3055 as a switch to trigger MJE13009 with Primary Vcc in collector. I have succeeded in doing so and manage to make it self oscillate. however I encountered a problem, 2N3055 is heating up, the trigger coil is heating up (because its in the outer most part of the Coil), the rest of the transistors is a little warmer than my hand. I believe I am wasting energy into heat, so I decided to increase its frequency by increasing the Trigger base resistance, I observed this also lowered my battery voltage. by the way I am trying to revive a battery 12V40AH gel-type.
1. If I increase frequency to eliminate the heat build up totally, the voltage of the battery lowers (consuming 50ma to 1A heat build up varies) if I remove charging batt. neon bulbs turns orange intensityvaries. ~~iiinnnnggggg sound
2. If I decrease the frequency I heat up 2N3055 and warm the MJE13009 (some does not even warm at all). (consuming 2A) if I remove charging batt. neon bulbs turns purple. ~~tssscchhhhh sound
this kind of frustrate me, I have tried setup no.1 to charge overnight only to see in the morning that it did not increase the voltage.
I have also tried setup no.2, voltage in the battery increases, but heat build up from transistors,coils bothers me.
what kind of sort of sound should I be expecting,
I also have lots of rechargable NIMH that I had revived without problems, I could also charge non-rechargeable 9V batteries
in minutes (just fluffy charge to power my multimeters.).
I Would really appreciate advice and tips on how to effectively charge/revive batteries. , or maybe improvements on my circuit.

, but this still, did not increase the voltage that much. so I tried Cap Dump "manually" (which is actually part of my build using NE555 but did not really completed.. Because.... I was fascinated to look at those Neon Turn Bright Purple when I unplug the battery instead of it going directly into capacitor. Maybe I'll just create a switch for Direct, Cap Dump Output.

) Can you go deeper with this?
