Hey guys, my dad had made me a preamp for a system he built for me. Unfortunately he died before he finished all the details. Many of you may have known him. His name was Bill. Anyhow, he put a remote control unit in the preamp. It is hooked up, but I do not know what kind it is and how I can get the information i need to make it function. Take a look at the picture i attached. Wondering if any of you can help out. Thanks in advance.

remote

Well I have to know when the power turns off and on inside the control for the remote to be programmed. Looks like I am going to have to learn the circuit before I can program the remote.The power is not hooked up to the remote pcb. It looks like i have toggle -> transformer for power. does it need to be parallel to function as one? Arrg
