Equivalent

[mohandes]

Hello
i go to buy the capacitor for my cscope but no body know what is they.in picture c28 what kind of?what is the voltage and value?50HY27 write on this
thanks

[mohandes]

ANd anothe is the teransistor
number TR102.
thanks

[Davor]

TR102 is a FET switch J113, and the capacitor is a foil wound one somewhere about ~100pF

Both seem to be in perfect order ?!

Hello Davor
ok now1- i need to Equivalent of them?
2-how you certain Values of the capacitor.can you tell me what are 150HY40 and 1000HY47 and 3nc R4ks and 20HY32 ?
if you Instruct me that is very good.
thanks

[Davor]

They are h48kpo, hr56det7 and wl6ft45

How the heck could I know that !?

The capacitors are measurable, you just have to yank them out an measure. Only if they are burnt and obviously damaged you guestimate. What are you actually trying to achieve?

Hello Davor
all of caps are burn.now i need too Equivalent of them?for example 150HY40 is 150uF and 40 volt.is it electrical cap or poly or ceramic?
you say They are h48kpo, hr56det7 and wl6ft45 , what is your mean
thanks

[Davor]

Isn't it obvious? I have no clue. Mujhe mAlUm nahin. If you are able to make a schematic diagram of the part of a rig where you have burnt parts, preferably with a photo to confirm validity, it will be possible to guesstimate a proper value to replace it.

Some capacitors have their value in pF followed by some combination of odd letters and numbers that may have some meaning to the factory that makes them, but are generally useless to the rest of us. The insulating material in the capacitors is responsible for their voltage rating and their temperature coefficient, but good luck finding what is what.

can you check this page and guide me

Observing those few pictures you posted I can't seem to find anything wrong. Unlike you, Guzzi posted lots of pictures, while your links lead to some odd Iranian pages with no content related to your detector, so I wonder ... are you for real, or you are just pulling my leg?!?
If you are for real, then you'll post a real description of your rig condition, whether you obtained it broken, or it broke in meantime, what happened when it broke, does it do anything, and if it does what it exactly is, and so on.

From the Guzzi's pictures, not yours, but Guzzi's, I can tell the detector was in it's youth about 1982, which gives it some 30 years of service ... what kind of service? Blazing sun or damp rain? Not used at all?

Those 2 pictures you actually posted show no problem at all! The upper side looks good. Nothing burnt. So problem can't be something that generally does not make trouble. So picking random parts will not lead you anywhere.

Again, are you for real? If you are, start providing some information!

Hello my dear teacher Davor
if you put email i send to your email.
thanks

if you want send a mail for me and i send to you my picture.becuse i cannot upload them but befor i send them for my friend Alain68700.
thanks

You can post pictures here, just go to "Go advanced" button and find "Manage attachments" there. You'd be amazed how keen eyes some people have.

So far I figured you must be Iranian - guess no one here has problem with that. I'm Croat and some of my best buddies here are Serbs, so don't expect enmity in this forum either. I like Iranian gaz, my XYL drinks Iranian green tea daily, we both love Iranian dates, especially the fresh ones.
Just go ahead

I apload my picture but yet I and my friend Alain have problem about the capacitor.please help.in my country have not j113 ?????????what am i do?I search about Equivalent but it have one Equivalent and the name is BSj113(the book name is A to Z)
regards

[mohandes]

And abut the capacitors is it ok?
about the capacitors I ask the seller of the electrical and he says to me those are electrical capacitor.for example 1000HY50 is 1000uF and 50 volt.but i think he said wrong.Are you searching about that?i ask about 10 seller but one off them help me.
thanks

There are some physical limitations to the capacitors production, so 1000uF can be only an electrolyte. A designation without pF or uF can also be in pF, so 1000pF is a fair guess for a small non-electrolyte capacitor.

As for J113, your best bet is finding another FET with similar Idso and I'd suggest BF245A, but I have no idea if those are available to you. What are the common types there? European, Russian, Japanese, or else?

The photos suggest that you have a big problem in your coil. Even if you assemble it correctly, you'd have to balance it as well. Those cables with insulating tape are not promising. Can you get a working coil?

The photos are of poor quality, so make sure you have enough light from diffuse source, say a white painted wall or a 1m*1m styrofoam, and make sure your camera is focusing macro (a flower symbol). When you see no detail on white surfaces (say electrolyte top caps) you may want to take another photo until it is right.
