I just found back my very first CPU.

(http://www.nvg.ntnu.no/sinclair/images/spec48k.jpg)
Sinclair ZX Spectrum

Problem: I lost the power adaptor.
So I'd like to buy or rebuilt it, but I don't know what to rebuild or where to buy it.
Any information about this AC Adaptor whould be very  
appreciated.

I'm assuming that this is an AC->DC adapter.  My best advice would be to look through whole lot of them and match voltages and amps.  Don't pu one too big in there, or it'll blow up, lol.

buy one of those "Universal" adapters from Radio Shack, they have like 8 adapter things, diffrent sizes and voltages...

this thing probably uses something bigger than that can provide, and is probably quite unique, and uses a custom jack.

From Sinclair ZX Spectrum introduction (http://www.solvalou.com/speccy_books_intro1.php)

"3. A power supply. This converts mains electricity into the form that the ZX Spectrum uses. If you want to use your own power supply it should give 9 volts DC at 1.4 A unregulated."

I take no responsibility for melted rubber :)

Just in case you didn't know... you can use a power supply with a higher rated current so long as the voltage is correct.  Too bad the article doesn't say what polarity you should use.  Is there something on the box that indicates which contact is positive and which is negative?

It doesn't  :(  .
Whould it be damaged if pick the wrong polarity(just for testing) ?

It depends on the piece of electronics.  I'd suspect the computer might be damaged by the wrong polarity.

Anyway, I looked this up on google for you.  It says the correct polarity.

What a neat little box that is. :)  I'd like to pick one up to pair up with my Atari 800XL.

They're still very cheap.
