If you live in Sweden BC, if you live in USA 2N. If not you can compare characteristic too.

Thanks =)

is what i suspected .i can buy both here in scandinavia.

bouth are 0.2A
info on 2n3904 say nothing about how many W.
On schema for xr71 there is used bc series..so i guess it`s ok to use any of them ..with no leek in performance ?
BC 546
TRANSISTOR SILICON NPN / 80V / 0.2A / 0.5W

2N 3904
TRANSISTOR SILICON NPN / 60V / 0.2A/B = 100-400

Use BC557 and BC546...

Use BC557 and BC546...

Thanks..
all done ,,i used bc ..suit good ..them i had a lot of at home

Hi, how do you tune DP in field? I don´t know, what to do. If i put pots to 0, then my DP beeps, when to max, sound disapears And detection is poor. I have 1x1 m coil, 15 turns, 0,7mm wire

you draw a problem why White's deleted CAVE mode from his new TM-808. why some guru leaves only 2 pots at panel, like Eric Foster in his PI detectors. for idiots many pots at panel go to an head illness only! althought you have 101 keys on your PC keybord and do not ask people of MICROSOFT why them are so much

delta pulse

what is all this about STTH1210D and 3 x 4700uf caps on some forums?? i cant find where it shall be on any deltapulse component overlay either on any schema i have untill now..
.what happend ?
I have not been in the shower since christmas because of this headpain.STTH1210D.so please answer somone so i can go to my bathroom and take a bath
.i am also making the 2 side delta pulse
after this singel side pcb
i am ordering STTH1210D from my contakt in china..so if anyone need hard to get components i can help members here worldwide
i succesfully got all my lf 357 and lm556 from china a week ago

Can anyone help me please To work well
I have used coil 60cm 0.5 mm and 25turn 7.5 ohm
What should I do
unfortunately not know the English language(40 page)

Hi Tuxnor,
I have a question, is metaldetecting in Norsk ilegal or not? Is dificult for me to find a job there? I´m from czech republic. My girlfriend love this country.

KT315: I must make my coil stabil and make some more tests. When i was testing before, it takes 1.5 M x 1M (i don´t know that word in eglish for it ) for 3 M with strong sound.

greetings! if you press the knob RESET (or PRESET) the sound would fall down in few seconds. if not - you have a problem. if yes, the sound falls down to zero level, then you begin to turn THRESHOLD pot before a moment the sound will reveal again in staccato style. then you slightly turn it back before the sound must be dissapear to zero again. you did get the tuning and can go to hunter out
try.

thinking, but not so clearly, you can find an analog of the diode, Ultrafast Recovery I look in datasheet, in any CRT oldie type PC monitors. I need to take a time-out for deep learning of this matter.

Hello my czech friend ..yes its legal in Norway ,,but not here in sweden
you need a premission for area, and what you are looking for,,
so i have bought a mineraldetector ar924 for use in prospecting here in sweden..so i may go around law ,,last time i asked premission from consil
office here,,they said yes and they did hardly know;n what a metaldetector is

I tell you this ,,its easyer to get a work in norway than sweden..depence on your proffesion of course..and its expencive in norway,,i moved to sweden
