ICs logo database

I think can help to identify components in reverse engineering.

Thanks Samogon, that's not a bad list there are quite a few logos I haven't seen before. I think there are still a lot of missing logos from from far eastern and also eastern european manufacturers, they're always tricky to track down.

I have around 12,000 various manuals for download athttp://www.electronicsrevived.com click on Downloads and then "Service Manual Archive"

All I ask in return if you sort out a directory or have a manual that is not there to go to ftp://rdp.electronicsrevived.comand upload the manual there. No exe etc.

Mentioned in another thread is TiN's collection of manuals. Added here so not missed when I get around to collating all links.

I can share my collection of T&M manuals and docs in return. (160GB).
Not to hijack thread, but I accept contributions too :D.

Parking another link:
I have a lot of old books (application notes, guides, magazines) , service manuals, schematics , datasheets etc on my ftp server ... here's the link

Code: [Select]
[url]ftp://helpedia.com/pub/temp/[/url]
It's anonymous ftp, you can download as much as you want, but anonymous accounts are capped to 1MB/s or something like that.

It's 124,358 Files, 8,390 Folders, 355 GB in total.  ... Server has about 10 TB of bandwidth and i'm only using about 4-6 TB each month.
@ mariush
Can we list your collection in this sticky too ?
https://www.eevblog.com/forum/repair/repair-documents-and-links-sticky-me-please-mods/

It's polite to ask.  ;)

Not sure if this is the right place to post to but....

Looking for the schematic/circuit for a Vision Engineering Alpha Microscope PSU main PCB.

I salvaged a much used and abandoned microscope for home use.
Initially the lamps were flickering at about 2Hz which I cured by replacing the main Electrolytic, but now at power up, the circuit takes several attempts to ramp up to full light level.

I have gathered up data sheets for the ICs and I am hoping that someone has a schematic/circuit diagram before I have to trace out the board.

I believe the problem area is the Triac (MAC223A-8-ON) driven by a Zilog (Z86E0412PSC) that produces the lamp level PWM?, so anyone with experience of this type of circuit I would appreciate hearing from you.
I have yet to start probing the board with my scope, but this will be my first use of it, so I am doing a lot of reading up before I start poking into a live board.

Thanks in anticipation.

Welcome to the forum.

It's not really but as a newbie we'll forgive you.  :)

You should start a new topic in this main Repair board and you'll get better visibility and more views.
Use the brand and model in the thread title and start the post by asking for manuals and/or schematics.
You might have to draw out the circuit and/or take some pics so others can help you fix it but those might be down the track a bit yet.
Good luck with it, seems a very worthwhile repair.

There probably are some more dead capacitors on the board, likely around 47-220uF, and replacing those should cure the problem.

For those new to scopes and CRO's the first few minutes if this old vid from Tek is useful to understanding the functions of moving an electron beam to create a waveform on a CRO display.
This simple explanation also helps one understand what might be involved on repair of CRO's.

Just dug up a manual, including schematics and parts-list, for a Power Designs 3K10B  3kV/10mA High Voltage Power Supply.

PDF is here:

The http://exodus.poly.edu/~kurt/manuals/manuals/ link doesn't work for me.

If you Google certain test equipment, you can find a direct link such as: http://exodus.poly.edu/~kurt/manuals/manuals/Tektronix/TEK%202445B,%202455B,%202465B%20Operator.pdf

There used to be a directory of all the manuals on the site but I can't find it. I have some Bruel & Kjaer test equipment and I believe I've seen some B & K listings in the past.

Anyone?

Lee

covers domestic household products and caters for a few different brands. Provided by statewide appliance spares, suppliers of tv boards and misc other parts who charge a premium price. Their service is good but it's often much cheaper elsewhere.

I found this link to the Arboga Electronics History Society Sweden Electronic Test Instrument Museum

https://www.aef.se/Instrumentmuseum/Innehall_instrumentmuseum.htm

It has info on Tektronix, HP and a bit of other stuff. It also has links to some manuals including service manuals on external sites. I include the link here because it might make a better index than some sites.

Also I did find a service manual here but it does not appear to be included in any index. I found it via google.

https://www.aef.se/Instrumentmuseum/Instrumentportal_ny/Dokument/Enstaka/9440_Protokollanalysator.pdf
A GN Navtel 9440 protocol analyser

Anyway I trust it will be useful to someone.

Hi!

I was looking for the components list for the Soviet Made C1-55 Oscilloscope I've just got as a repair project, it proved impossible to locate any until I put the Cyrillic word for Oscilloscope into a Google Image Search!

If your looking for Russian Test Equipment Documentation, (beware - it'll be nearly all in Cyrillic!!!) try this site:-

http://www.kiprip.ru/help.html

I finally found the parts list I wanted on this site!

Chris Williams
It's an enigma that's what it is!! This thing's not fixed because it doesn't want to be fixed!!

I've been looking for the service manuals for the BK Precision 1590a.  I can find the schematic/parts manual and the owner's manual, but the service manual is very hard to find. (I do know that it exists though!)

I have gone through every website listed here and more. Any help is appreciated!
