Nigel Goodwin Super Moderator Most Helpful Member Jan 17, 2024 #4 Well the picture seems to have vanished?, but as I recall, there was an opto-coupler, a slide switch, two sockets, and two resistors. The only issue might be locating the same slide switch, and perhaps the same jack socket. The opto-coupler and resistors are standard parts. Upvote 0 Downvote

Tony Stewart Well-Known Member Most Helpful Member Jan 18, 2024 #5 Optocouplers will work if the load R pullup is raised to be 10x the drive Rs when used at the same voltage. this may increase risetime due to load capacitance and more details are needed. Upvote 0 Downvote
