I have a couple that came out of Centipede games...the once I have has A035888-01 stamped on the side. If it's not the same one you have let me know the # and I see if I have one. $20 plus shipping from MN.
Sorry, all the once I have are the A035888-01. According to "Elektron Forge's" website the A035888 is for Centipede games but I'm starting to think the info is wrong. One of the once I have I know I pulled out of a BZ game, I even marked it as such and it has the A035888-01 stamp on it.
You better look for the one you already have in there or you may have problems with the pinout not matching. Here is the website for more info: http://www.elektronforge.com/transassy.htm but like I said, I think some of the info is incorrect.
