Destroyed My Daiwa PS-220 Power Supply

What most people do here is posting the pictures by uploading them to some website like flickr and providing a link.

Fred:

Either go to Photobucket.com or Google Photobucket.com and go to the Photobucket website and set up an account.  All it requires is a screen name and password.  No charge.

You then upload anything you wish including pictures or schematics to your account page and then as you view what you have posted, "copy" the URL at the top of the page and paste it to this forum.  Then anyone who wishes to view your postings can click on the link you post.  This is how it's done.

If you can, use another site (such as tinyurl) to upload the file to, then simply type the address of that link when you post your message.  That's the best and easiest way other than getting the other person's e-mail address and e-mailing it directly.

I'm back - but still up to my curly locks in gators! (At least what's left of 'em - curly locks, that is!)

I created an account on Photobucket and uploaded the 'jpg' file of the schematic.

Now, Google Chrome could not do anything with either string for HTML or IMG, for whatever reason.

One thing that bugs me is that with my local 'jpg' file I can roll the mouse button and expand the image considerably.  Makes it a lot easier to read.  But that doesn't work when looking at the Photobucket image. 

Can the actual original 'jpg' file be downloaded from this website? 

*ONE TIME* when I was flipping through the PHB screens I got one that had a small block of text immediately below and to the left of the main diagram image, and when I clicked it I think I captured the original image because when I opened a new (Chrome) browser window, I got just the whole image, AND I could re-size it!  But I never saw that Dang screen again despite MANY attempts to find it!

Also, I don't think I remember seeing that small blue-bordered image centered below the big image, but I could be wrong on that.  Whoever said "Ignorance is bliss!" is Plumb full of it!

So, does anyone know how to retrieve the original file (intact) from PHB (hopefully)? 

I'm having so much fun here I can hardly stand it!

I just couldn't give up yet. 

Found out that if you right-click on the image and then click 'Save image as', you can retrieve the file, and re-size it.  Unfortunately it doesn't appear quite a crisp as the original file, but it is readable when increased.

I'm certain that is NOT what I did the first time, tho.  Dunno why it lost some of the clarity when downloaded.

Thanks a lot for the picture. I could not download it via the right click. However, when you use the options key above the picture you can select download.
I roughly compared it to the schematic of the PS-304 which I got and it is mostly a difference of the pass transistors. The regulator boards are the same. So my recommendation is still to first check out the voltages as provided in the schematic. If this checks out good (most likely), you can get to the pass transistors.

Fred:  I finally got a look at the schematic.  When I blow it up I still have a problem with some of the characters so you'll have to translate what we say.

Right off the reel I'd test the two 2SC3281 pass transistors and the 2SC1173 driver transistor. 

Next would be the 2SC1815 driver transistor and then the PC324C IC.  The number on the IC is very illegible to me.  The 8 is underlined because I'm not sure it's an 8. 

Let us know what you find.
