Mohandes are you saying you dont want me to send you the parts ?

first thanks mr starmol my friendmr 6666 look this site http://www.taydaelectronics.com/mpf1...ransistor.html MPF102 is 0.45$(equal 1500Toman for iranian)2N5485 is 0.28$ .BF256 and BF244 are 0.24$can you send me these transistor by these price>thanks

[mohandes]

no body here....

Mohandes
you asked people to help you to get some components,
I offered to post you some at the retail price I have to pay at my local electronics shop.

My local shop cannot match the price you can buy them for from http://www.taydaelectronics.com/mpf1...ransistor.html.
so you will have to get them from TaydaElectronics.com.

When you buy from TaydaElectronics.com be aware they have a USA $5.00 minimum purchase,
plus shipping,
You can see shipping costs and available shipping methods to your country using "Estimate Shipping Cost" box in your shopping cart.

Good luck

Postage cost from England to Iran is very exspensive You would have been better off takeing up 6666 kind offer and let him supply you with parts required.
This thread has gone stale and boring due to the same repeated questions, and I for one has put a lid on it .
Please can we get back to some normality here.

Hi all guru
i have ? about the SUFFIX ,A,B,C after the name of transistors?
are good BF256C Or BF256B for baracuda (which SUFFIX is better)instead MPF102??

and what the different of BF256 and BF256B??????????
thanks

Hello Mohandes, remove the fet shown in the photo, it will work better.

Hello Mohandes, here in Brazil is easier to find the fet fet BF245C I replace MPF102 and 2N5485 for him, careful pinning it should be welded with 180 degree rotation.

hello to all current baracuda builders here

here can i seta longer pulse width at th ic 40106 ? after pin9 + variable ressitor?

[mohandes]

Hi all
i upload my pics about the baracuda.help me.why not have sound in my detector.
i replace all mpf102 to bf245b.
and use bf256 instead 2n5485.
i use coil 451mkh and 2.2ohm.parallel res 330ohm.
i think pin 6 ne5534 not good(can not detect)ok?????????
regards






edit :
how can i adjust pin1 tl082 on 0volt, i want set it by multiturns but i can not succes.
please guid me

Hello Mohandes, adjust the delay as pictured.

[QUOTE=Wilson;176978]Hello Mohandes, adjust the delay as pictured.

thanks wilson
i do that but yet have problem ,have not sound!!!

mr Apberg say(many ago time) should adjust pin1 lf412 on 0volts.but how i can this?
i think wave for ne5534 not true?is it ok?

[Wilson]

Hello Mohandes, you must adjust the zero on pin 6 of the IC NE5534 and not in the LF412 pin 1, the adjustment should be done with the coil connected and away from metals. Adjust the trimpot ofset IC NE5534 with a multimeter measuring AC in scala pin 6. You can also use the oscilloscope, centralizing the cycle positive and negative, that does not mean that the pulses from pin 6 to disappear.

hi wilson
thanks , i try too that but in AC show 0.75volts and on DC 0.335 volts (not change value on ac or dc points when i measure by multimeter)
why do put on AC point the multimeter and not DC point?!!
regards man and sorry me.
