Thanks,
I guess what had me really confused is that the serial number is very low and I have seen ones with higher numbers with the Renticon.
It has hand written 12v on the plug in. Do you think that was a mod later. I thought these things were 18v.

Well you need 18V in and it will make 15V out of it. Can you take a pic of the entire board so I can have a look. Just want to know if it has a 7815 or LM723 voltage regulator?
