Stivep1: Tesla Rehash (Akula device)

[d3x0r]

baroutologos;
The total inductance of the coil (connected in the bifilar configurration) is 30.7 mh. The waveforms (coil performance) seems to be similar to what is shown in the videos.

I was trying to get a better understanding of the Transmitter and Reciever Controller Circuits. Do you know what the KT555TB9 Chip is, and if there is an english (or translated) version of the spec sheet?
As Always; Thank you and have a great day.

Thats what I also thought at first. Started doing some digging and found this;

JK-?. ?:K555TV9 JK Trigger.gif .... Single D-type flip-flop with set and reset; positive edge trigger. Rev. 10 — 2 December 2011 Product data sheet.

- Haven't found a pinout for it yet (in english). Tried to cross it to other  D-type flip-flops (like the 40270 which has only 14 pins insted od 16. Still looking .
As Alway; thankyou and have a great day.

Anyone:
The below attachment show the information I found on the KT555TB9 chip (used google translater to translate text) but could not seem to determine what pins #7, 14, and 15 are. Does anybody have any idea of what they are.

As always; thank you and have a great day.

Hi,

You write KT555TB9 in your text but it is K555TB9, okay? (There is no such device as KT555TB9)

Pin 7 is supply voltage negative (or common ground)
Pin 14 is Clear 2 (or Reset 2) input
Pin 15 is Clear 1 (or Reset 1) input

This IC is said to be equivalent to the SN74LS112N dual JK flip flop  http://koapp.narod.ru/tehlit/hardware/22remontpc/t012.htm 

see this too:  http://www.evita.lt/en/p-catalogue/id-1/sel-142/st-700/russian-integrated-circuits_700.html#cat and data sheet :
