It pushing a little over 350vdc rectified with little tuning and messing with. 52 winds each side off the pickup and 10 on the collector coil/2 on the base!

32.2 Ohms off my 500 Ohm POT

2N3005 power transistor

Before you add the other side, could you check the output voltage using a diode and capacitor and then reverse the diode and see what the voltage is. My coils all give a very high voltage with the diode in one direction and a low voltage with the diode in the other direction.

Here are the results for my 2B-10C-80P coil. I would call your coil a 2B-10C-104P coil. They should be somewhat close.

Also, was your taransistor a 2N3005 or a 2N3055?

Sorry I know I never include this info.

its ok. I forget to say I am only using the pickup!

Input by protek powersupply ..
1.5 volts DC/.500amp

well, xee2 is not objecting, but I need to ask.
Is there any way for this power supply to sneek a little extra amperage into the circuit if it calls for it?

And, how could you tell?

I am still puzzled about why you have no trouble starting this up. or rather, why I do.But maybe a little surge is available?

Also, I will change the primary on mine to 2T,10T  because the pickup has 240Turns and would be very close to both of yours.

I may have better luck this time than before.

Thank you for your good work and beautiful pictures,

@xee2,
Wow,
Those are great tests. Thank you.
You answered many question in one little gif!
a gift of a gif. 

And are you always using a ceramic cap here? You already told me it was OK to use the can type which is polarized, but I am just checking.

thank you. this is great!,

It is always better to use an unpolarized capacitor if possible. I am using polarized capacitors for the battery caps and unpolarized at the voltmeter.

just cuz i like this coil ... ill add 2 more pics .. 

this one has the mk2 transformer windings on it ...  next i will add the mk2 generator windings on it ...

i will dubble the windings on that one .. 

soon as i get it wound i ll build the jt's all npn ...  but it dosent matter as i see it you need a second unit pnp doing the same thing ...  but 1 at a time lol

the windings showen will get rectified to a SUPER CAP  would be great but the only ones i had were small and sent out ..   

so ill just use some RECHARGEABLE BATTERIES...   and run from the source till they are charged then switch to them ..  and let the SOURCE recharge ..   

the 5 mk2 generator windings are additional outputs...

ist!

i fininshed all the mk2 windings ..  there 10 mk2 windings on this toroide now ..  5 are transformers/ feedback coils ..  and the other 5 are generator coils .. output ...

and for my next wire act ....     lol   i will add 22 ga magnet wire in laps 5 laps right ontop of the generators .... 

then tommorow ill build all the electronics of it ....

sure is a busy little cridder lol ......
