i think its aaa bro coz reading that thread next to it is bro bill's post saying its aaa fuji circuit
the one you showing is working coz thats the way i do it by following this long thread . the problem is i cant post it here coz i send it to my friend as a gift hahaha.
the one i have now is the first fuji i have. i have 3 different fuji and all of them is different circuit weird hah.
well by reading all your post here and helping us is one great things for learning ..

i just look at the parts on the boards and compare them to ones at start of this thread that have allready be documented

thanks very much for directing me directly to the modification post. i compared my aaa fuji board with the board in the post and think, as gadget said, that they are different boards. the help i get here is really great!

just follow what they saying bro they also help me here and i learn by following them also
they are also my prof here big thanks to them..

Hi Djoey . That link is  old AA mods i believe  , what i show is AAA version that temp has . IF its got an LED instead of a Neon this most likely its not the old aa version so those mods do not apply.
Thanks

tnx very much gadget! i understood as follows:

step 1: remove the 350 volt cap (already done)
step 2: short out D1 (diode 1) with a jumper
step 3: short out the " copper stripe button"; this can be well seen in your picture "aaafugimodded"
step 4: i don´t understand clearly; i will remove R2 100 ohm and replace it with a 5 kohm poti. the two outer legs of the poti i will solder instead R2 but where i do solder the third leg of the poti

question: on picture “AAAmodtop” it looks as the upper leg of R3 15 ohm is soldered to the lower thin copper stripe and the lower copper stripe is connected with the upper copper stripe. is this correct?

@dasimpson

i am not used to handle a forum. therefore i am a bit slow ;-), sorry for that. the board in the mentioned post looks really as my aaa fuji board and the resistor values are the same. here is my interpretation of these pictures :

+ 350 volt cap is removed
+ the negative end of diode 1 is loosened and goes to a capacitor, but which capacitor? or goes it to one end of the cfl?
+ then a wire goes from the lower end of R1 4,7 mohm to the other end of the cfl. is this correct?

where is the difference to the modification of gadget?

thanks
