What was making the battery run down in between tests?

The battery was running down during the tests because the circuit was draining power from it. In between the tests the battery was allowed to sit with no connection and it recovered some of its voltage because batteries do that sometimes.

well i hope to improve the out put of it

i was kind of thinking 3 wire picup up or output winding useing 2 of the 3 for a mk2 style picup and 1 for jt flyback recovery/transformer action   the fly back should be transfered via the other 2 wires in the pickup ... 

2 the load ... 


ist!

I wanted you to prove to me that your 2T,10T,80T bigboy would do what Theory said it could.

  What theory? What are you expecting it to do?

@ resonanceman

People have done both. I have always used the approach in your second circuit.

Thanks  Xee

I am putting my  modified tank circuit here

I  am working on  adding more   parts  to show  the whole  circuit

I removed  the  original  JT LED  because it goes out when the blue cap is added

I also added a  secondary because that is the way this  circuit should  be used

If you had just put a freshly recharged NiMH AA into the circuit and run the thing until the light went out and told me the amount of time, my question would be answered.

I do not understand why you want me to do this. But I will. However, since I do not like watching tubes, please make sure I understand what you want done. My understanding is you want me to run the following circuit using a fully charged battery and see how long it will run before the tube turns off. Is that correct? Or do you want me to use an AA battery?
