Transistor Identification help requested

Hi. I actually needed some help identifying some transistors but I see that I can't drag n drop the pictures of them into the text unless I missed something

Sorry

Bottom right, centre tab, upload a file for url photo or on more options it will show a tab to add attachments.

OK and thanks except that it keeps telling me that there's a problem uploading the files. It goes a full 100% and then gives me the error message. Tried a few times with a few different files. Is there a time limit before a new member can upload a file or a size limit?

They are probably way too big
100kb max and 800x600 max as a guide

anything with those sizing's will drag and drop in an instant

OK. I suspected something like that. I'll have to downsize them. Right now they are between 2.2 and 2.5 Mb in size. I'll have to do that over the weekend so I won't be trying again until next Monday. Hope they don't lose too much detail. Had to use a 30x jewelers glass over the camera lens so the detail was clear. Thanks.

One way I did that quickly is to put them on the screen, small-ish, and use snipping tool or similar to cut them off the screen. Instant downsize and with resolution that you can see is ok.

Want to try supplying the characters written on the transistors?

Can anyone identify these 14 transistors. I've been going thru the inventory of a closed repair shop and of the many hundreds of transistors that needed to be identified I could not find out what these were. I am looking for the JEDEC or Japanese industry number or TCG/ECG or NTE number. I have already tried "Googling" and NTE's cross reference but these so far have defied identification. Here are the markings in order of the pictures (top to bottom, left to right):

1) GE 046-5 7835
2) TI 1304 7411
3) LX188
4) GE84 185
5) MSPS 686
6) A8K 274 CG 7840
7) C(or G) 28-5 RCA HNZ 8025
8) GE 098-1 421
9) 100-1 274 H A8102
10) LX189
11) D1C M(Motorola logo) 311
12) 9033 M(Motorola logo) 021
13) D3G M(Motorola logo) 351
14) NS437 776-2

Sorry for the above reply. I did convert the pictures to a smaller size but they were in .BMP format. Didn't know the site doesn't accept that format. Anyw3ay, yesterday I was T-boned by a lady who ran the red light and it broke my clavical. I have to have surgery to repair it so I won't be visiting the site to finally get those pictures up. Probably 4-6 weeks. Wish there was a cancel button because I would have aborted the above reply. See all of you later.

Hello,

The site will accept jpg and png pictures.
Images upto 300 K should be no problem.
You could convert the pictures in a paintlike program.
If you also want to manipulate the pictures, you could use GIMP.

OK, let's try this again.

Just try googling the part number followed by the text "Datasheet" and see what happens. If no results then that is probably the end of the line unless any one seeing this post and who may have the required info responds.

OK. Thanks.
