I'm looking to you electronics experts to help me source a variable resistor. I've searched google, electronics wholesalers, and the like to no available. I'm from the US, but living in Australia right now, and the pickings are slim regarding full on electronics stores. I'm looking for a resistor with the following specs; 1X variable 0 to 1k ohm resistor 50VAC rated 0.05W or more. Pretty simple right? I want it to be like the one pictured below, I will have to do my own sealing/waterproofing as it will be used for automotive purposes. Any help? TIA Ω
