Hi haikel774
                        adding a small series resistor (2 to 4 ohms) with coil.

Hi xavier

           Depending on the program coil calculator gave me  inductance =1.961 mh.

best time

OK that makes sense I used the 0.5mm wire 21 turns on the DBP2010and I have more or less the same inductance.

All the best

Yes but remember that this calculator is not for jumble wound coils so the inductance will not be the same once you have wound your coil for this reason it is better to have an inductance meter. You can build one quite easily and it is inexpensive. I should still have the schematic some where so if you want it I could post it for you.

thank you very much

Hi haikel774   
 Check the IRF740 if IRF 740 heats up check the 556, r6=1k.  r5=680/1w,adj.pr1 and dont touch,c30+c31+c32 =10000 uf/25v, Please Check the pcb, adding a small series resistor (2 to 4 ohms) with coil

step by step it is worked good. any help............

best time
