Emax

Well- my friend  (he is a Electronics Tech in industry for 25 years) I  
called tried to cross the item. It is not in the Japanese cross  
reference. This is what is called an "in-house" part. A company stamps  
a number on a device that is really only used "in-house" as a part  
number and is never released to anyone save an OEM.  If released  
generally it is given a different number. This is most likely why it is  
not cross-able. He also said from the diagram that it is not  
necessarily a TRIAC either, it could be a DIAC or MOS-FET. On  
non-cross-able items the diagram may not really be what the item  
is.....He informed me that TRIACs are almost never used in a power  
supply. (save when used as a "crowbar", but that is not an industry  
accepted practice to do...) He has access to purchase obsolete items as  
well (He makes major IC component purchases for a large (200 site)  
Amusement Company). He could not source the part. If you ever found it,  
it might cost as much as $40 plus shipping. That is a big IF

The solution he recommended was to buy a small power supply and replace  
the old PSU. Others have done this here on the group, I believe.

I am assuming it is an +5 and +12 power supply (without actually  
opening it up- can anyone confirm this?)

With that assumption: here are some options......

www.bgmicro.com look at page 13 of their catalog- cheap and looks  
promising.... the A+ switcher on this page.....
www.jdr.com has open-frame power supplies.
http://www.allelectronics.com/cgi-bin/category.cgi? 
category=480&item=PS-4350&type=store

These are all in US- but should give you some ideas....heck bgmicro  
even takes paypal....

Hope this helps,
Ted




You are looking to provide +5 and +12
