H hessa59 New Member Apr 1, 2017 #1 I have inherited a E&L LD-2 pencil box electronics trainer. I am trying to modify it to work with 3.3 volt microcontroller circuits. I have found the manual online https://ctemedia.s3.amazonaws.com/gs/discontinued/files/LD/LD-2 Manual.PDF but it is missing the schematic. Does anyone happen to have a manual with a schematic for one of these old gems? Any help would be greatly appreciated!
