@ Conrad

These are the pins I use on the $4 Electronic Goldmine flyback transformer. There are no standard pin assignments for flybacks, they all seem to be different.

Hi all ,I was just asking this in another thread,Xees your diagram only shows 5 pins in use what are the other ones for?? I have very little knowledge about these just that they ethier step up or step down,either voltage or current but, not both.....thanx     ..shylo

Sorry but photo just wont work with my terrible camera - ive been trying to take one but just cant get the letters in focus.  Heres whats printed on it

''159S-06-33AS
  0607.  F    C''

on a different side in big letters:

''1059  S''

and

''SAMPO''


and FOCUS next to a screw, and SCREEN


Its working very nicely now with a long and thin 14W cylinder CFL.  But im sure theres plenty of room for improvement 

Good luck!

PS  Ill measure ohmic resistances on my coils after Monday when ill get a chance to visit the radio market and buy a new multimetre.......and some new caps i think too

I have no idea what the pins are for. There is no data sheet. This is how I have been using it.

@ shylo, flathunter and xee2:   concerning fly-back transformers

There is some information on the pins of a fly back transformer:
http://www.electronicrepairguide.com/flyback-transformer-pinout.html

Flathunter's flyback seems to have the part number SAMPO 159S-06-33AS,
shylo's flyback seems to have the part number SAMPO FE1B4OAT
(but that did not help to find anything).

http://www.sampo.com.tw/  -- Is there a reader of these posts who can read Chinese, one should be able to get some info from SAMPO?

Here at least some diagrams of Sampo fly-backs:
http://www.donberg.ie/descript/h/hr_7692.htm (click on the GIF-image, only negative pulse on pin 4)
http://www.donberg.ie/descript/h/hr_46088.htm (click on the GIF-image, three nice pulses on pins 6,8,9)
http://www.donberg.ie/search?query=SAMPO&wordflag=and&maxlines=100&group=00 (gives many SAMPO fly back diagrams, one can search for other manufacturers too)
They are probably completely different to shylo's and flathunter's SAMPO-flyback, but may be they use similar pin-outs on many products (like a habit within a manufacturer). One sees that not all 10 pins are used. The HV side looks interesting, diodes, capacitor, even resistors.

It is probably a good idea to buy the $4 fly-back from Goldmine in order to know what one is dealing with.

xee2 could you please post the names of the pins, as they are called in the specs or datasheet of the your $4 Goldmine fly-back (to compare the pins with the description at http://www.electronicrepairguide.com/flyback-transformer-pinout.html or http://www.donberg.ie/descript/h/hr_7692.htm). Sorry, I see that Goldmine does not provide any info (what a bummer).

Kooler in the thread "GBluer(Slayer) Exiter" describes a Slayer Exciter with a fly-back that runs on 1 Volt (he removed the core). This 1 Volt operation of a fly-back to drive a CFL interests me very much and is the reason why I ordered ten fly-backs and why I nag people about their fly-backs.

I appreciate all information (specially about the right pins to use) from experimenters who successfully used a fly-back transformer in a Joule Thief type circuit. My guess:
AFC pin (Automatic Frequency Control) and GND pin --> trigger coil on the base of the transistor. May be "horizontal collector pin" could be use instead of AFC pin?
B+ pin and VCC pin --> collector coil.

I should get 10 surplus fly back transformers for PC-monitors (CRT) any day now. Then I will try really hard to get some data about them.
