Unknown coin door with 2 pots and small button inside
(1/1)
dirkomatic:
I have a coin door from an unknown machine that has two pots and a small button on the inside. Does anyone have any idea what these might have been used for? I understand that one pot on a coin door is commonly used as volume. What is the other one and what is the button?
How can I determine if these are linear or logarithmic taper pots? 5K or not?
Thanks for any info!

Pictures always help.

Button could be the service mode switch.

I realize that, but I didn't have a camera handy at the moment. I've got a picture of the pots and switch attached. I'll get a picture of the front of the door posted soon.
I did discover that they are linear, 100 ohms 2w pots RV4NAYSD101A from Precision Electronics http://www.precisionelectronics.com/MIL%20Style%20RV4%20PDF%20Download_files/MIL%20Style%20RV4.pdf. What are these for? I thought volume pots were logarithmic taper...
Service mode switch does make sense...

Could be from an older dual-speaker game with individual volume controls.
